 Yes, a right triangle can have two equal sides. The longest side is called the hypotenuse and the other two sides may or may not be equal to each other. A right triangle that has two equal sides is called an isosceles right triangle.

## Is two sides of a triangle are equal?

An isosceles triangle therefore has both two equal sides and two equal angles. The name derives from the Greek iso (same) and skelos (leg). A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle.

## What do the sides of a right triangle equal?

If a triangle is a right triangle and it’s isosceles, then the two sides other than the right angle must add up to 90 degrees and they must be equal, so each must equal 45 degrees.

## Does a right triangle have all sides of equal length?

As you can tell from the name of the triangle, this right triangle has interior angles of , , and . Since two of the angles of this triangle are equal to , the triangle is an isosceles triangle. Being a right triangle, this means that its two legs (the sides of the right angle) have equal length.

## Does a right triangle have 2 equal angles?

The two sides adjacent to the right angle are called base and perpendicular. The sum of the other two interior angles of the right-angle triangle is equal to 90°.

## What is a triangle called with no equal sides?

A scalene triangle has no equal length sides. It also has no equal inside angles. These triangles can be acute (all angles less than 90°), right-angled (one angle is 90°), or obtuse (one angle is more than 90°).

## When two sides of triangle are equal what is the third side?

Finding Third Side of a Triangle given Two Sides

According to Pythagoras Theorem, the sum of squares of two sides is equal to the square of the third side.

## Can a right triangle have 3 equal sides?

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

## Does a right triangle equal 180?

The sum of the angles in a triangle is 180. A right triangle has one angle of 90. Thus, the sum of the other two angles will be 90.

## What are the rules of a right triangle?

• One angle is always 90° or right angle.
• The side opposite angle of 90° is the hypotenuse.
• The hypotenuse is always the longest side.
• The sum of the other two interior angles is equal to 90°.
• The other two sides adjacent to the right angle are called base and perpendicular.

## What type of triangle has exactly 2 equal sides and one right angle?

• One angle is always 90° or right angle.
• The side opposite angle of 90° is the hypotenuse.
• The hypotenuse is always the longest side.
• The sum of the other two interior angles is equal to 90°.
• The other two sides adjacent to the right angle are called base and perpendicular.

## What are 2 equal angles called?

Those with two equal sides are “isosceles.” Those with three equal sides are “equilateral.” There is no direct connection between the size of the angles of a triangle and the lengths of its sides.

## Are all right triangles isosceles?

Answer and Explanation: No, not all right triangles are isosceles. Although it is possible to have a right triangle that is an isosceles triangle, not all right triangles…
