# What Is an Isosceles Trapezoid?

A trapezoid is a quadrilateral with two parallel sides and two non-parallel sides. An isosceles trapezoid, also known as an RSTV, is a trapezoid that has two sides with the same length. The two sides are referred to as the bases of the trapezoid. The other two sides of the trapezoid are called the legs of the trapezoid. These two sides are not equal in length, but they are still equal in size. The angles of the trapezoid are also not equal, with one angle being greater than the other.

## How to Identify an Isosceles Trapezoid

An isosceles trapezoid can be identified by the following characteristics: two sides with the same length, two non-parallel sides, two unequal angles, and two equal angles. It is important to note that the two angles that are equal must be opposite each other. Additionally, the two parallel sides must be the same length. The angles of the trapezoid should be looked at carefully to ensure that it is an isosceles trapezoid and not another type of trapezoid.

## The Properties of an Isosceles Trapezoid

An isosceles trapezoid has several properties that make it unique from other trapezoids. The two bases of the trapezoid are always the same length, and the other two sides are not. This allows for the two equal angles to be opposite each other and the two unequal angles to also be opposite each other. The diagonal of the trapezoid bisects the two equal angles, making them equal. Additionally, the two legs of the trapezoid are not equal in length, but they are equal in size.

## Uses of an Isosceles Trapezoid

An isosceles trapezoid can be used in everyday life and in the classroom. It can be used to solve math problems and to help students understand geometry. Additionally, it can be used in architecture to design buildings, bridges, and other structures. The properties of the trapezoid can also be used in engineering to help build various objects.
