**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…
