A right triangle can also be an isosceles triangle–which means that it has two sides that are equal. A right isosceles triangle has a 90-degree angle and two 45-degree angles. This is the only right triangle that is an isosceles triangle. … Another interesting right triangle is the 30-60-90 degree triangle.

Is any 3 sided polygon a triangle?

A three-sided polygon is a triangle.

There are several different types of triangle (see diagram), including: Equilateral – all the sides are equal lengths, and all the internal angles are 60°. Isosceles – has two equal sides, with the third one a different length.

What do you call a triangle with 3 equal sides?

Equilateral. An equilateral triangle has three equal sides and angles. It will always have angles of 60° in each corner.

What is a 45 degree triangle called?

For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an “angle-based” right triangle. A “side-based” right triangle is one in which the lengths of the sides form ratios of whole numbers, such as 3 : 4 : 5, or of other special numbers such as the golden ratio.

Is it possible to draw an equilateral obtuse triangle?

It is impossible to create an obtuse equilateral triangle. The word ‘equilateral’ means equal sides.

Can an obtuse triangle have a right angle?

A triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute. Therefore, an obtuse-angled triangle can never have a right angle; and vice versa. The side opposite the obtuse angle in the triangle is the longest.

What is the greatest number of obtuse angles in a right triangle?

Johnson Z. A triangle can have a maximum of 1 obtuse angle.

Why is it difficult to create an obtuse equilateral triangle?

The angles in an equilateral triangle are all 60 degrees. since all three angles are equal divide the total degrees in an triangle by 180 by 3. An obtuse angle is greater than 90 degrees. 60< 90 so an equilateral triangle can not have an obtuse angle.

Is it possible to draw a triangle with two right angles?

No, a triangle can never have 2 right angles. A triangle has exactly 3 sides and the sum of interior angles sum up to 180°. So, if a triangle has two right angles, the third angle will have to be 0 degrees which means the third side will overlap with the other side.

Is it possible to draw a triangle with two obtuse angles?

No, a triangle cannot have 2 obtuse angles. The definition of an obtuse angle is an angle with a measure that is greater than 90°.

Can 30-60-90 angles make a triangle?

A 30-60-90 triangle is a special right triangle (a right triangle being any triangle that contains a 90 degree angle) that always has degree angles of 30 degrees, 60 degrees, and 90 degrees. Because it is a special triangle, it also has side length values which are always in a consistent relationship with one another.

What are the side lengths of a 45 45 90 triangle?

A 45°-45°-90° triangle is a special right triangle that has two 45-degree angles and one 90-degree angle. The side lengths of this triangle are in the ratio of; Side 1: Side 2: Hypotenuse = n: n: n√2 = 1:1: √2. The 45°-45°-90° right triangle is half of a square.

How many right angle does a triangle have?

A triangle can have at most one right angle, or an angle that has a measure of 90°.

What is the name of the longest side of a right angled triangle?

The longest side of a right-angled triangle is the hypotenuse. The hypotenuse is always opposite the right angle.

What are the 3 angles of a right triangle?

Right triangles are triangles in which one of the interior angles is 90 degrees, a right angle. Since the three interior angles of a triangle add up to 180 degrees, in a right triangle, since one angle is always 90 degrees, the other two must always add up to 90 degrees (they are complementary).

Can a triangle be isosceles and right?

Can an isosceles triangle be the right angle or scalene triangle? Yes, an isosceles can be right angle and scalene triangle. Isosceles Right Triangle has one of the angles exactly 90 degrees and two sides which is equal to each other. Since the two sides are equal which makes the corresponding angle congruent.

Does every triangle have to have an acute angle?

Yes, all triangles have at least two acute angles. Acute angles are angles that measure less than 90 degrees, while obtuse angles measure greater than…

Does an acute triangle have equal sides?

An acute triangle has a measure of its angle always between 0 degrees to 90 degrees. The measure of its three sides can be equal, unequal, or any two sides equal. When an acute triangle has three angles measure less than 90 degrees with all three equal sides it is termed as an equilateral acute triangle.

How many right angles are in an acute triangle?

The right triangle has one 90 degree angle and two acute (< 90 degree) angles. Since the sum of the angles of a triangle is always 180 degrees...

How many obtuse triangles are there?

There can only be one obtuse angle in any triangle. This is because the measures of the interior angles of a triangle always must add up to 180…

Drawing the altitude of an equilateral triangle decomposes the equilateral triangle into 2 congruent triangles. They are right triangles with acute angles of 30 and 60 degrees. These congruent angles make all triangles with angles 30, 60, and 90 degrees similar by the Angle-Angle Triangle Similarity Theorem.

Is it possible to draw an equilateral right triangle?

We know that, sum of angles in a triangle is 180∘ and the triangle to equilateral all the sides should be equal and all the corresponding angles also should be equal. … So, it is not possible to draw a right angled equilateral triangle.

Can a right triangle have two right angles?

No, a triangle can never have 2 right angles. A triangle has exactly 3 sides and the sum of interior angles sum up to 180°. So, if a triangle has two right angles, the third angle will have to be 0 degrees which means the third side will overlap with the other side.

Can an acute triangle be a right triangle?

In any triangle, two of the interior angles are always acute (less than 90 degrees)*, so there are three possibilities for the third angle: … Less than 90° – all three angles are acute and so the triangle is acute. Exactly 90° – it is a right triangle.

Can an obtuse triangle be a right triangle?

Special facts about obtuse triangle:

A triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute.

Is an obtuse triangle always a right triangle?

An obtuse angle is one that measures more than 90°. A right triangle has a 90° angle. The sum of the three angles of a triangle equal 180°. A triangle cannot have two 90° angles, there an obtuse triangle is NEVER a right triangle.

What is a 45 degree triangle called?

For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an “angle-based” right triangle. A “side-based” right triangle is one in which the lengths of the sides form ratios of whole numbers, such as 3 : 4 : 5, or of other special numbers such as the golden ratio.

What does an equilateral right triangle look like?

An equilateral triangle is a 3-sided polygon (enclosed shape) that whose sides are all congruent (equal in length). An equilateral triangle also has 3 congruent angles, all 60˚ in measure.

Can you always form an equilateral triangle by reflecting a right triangle?

In other words, can you always form an equilateral triangle by reflecting a right triangle?” Explain your reasoning, No. The right triangle must have a 60° angle. ] … One way to justify this is to show that all 300-60°-90° triangles will be similar, so the ratio of the longer leg to shorter leg must be equal.]
