# What Is an Isosceles Trapezoid?

A trapezoid is a four-sided shape with one pair of parallel sides. An isosceles trapezoid is a special type of trapezoid in which the two non-parallel sides have the same length. It is also known as an isosceles trapezium, especially in British English. In other words, an isosceles trapezoid is a quadrilateral with one pair of parallel sides and two sides of equal length.

## How to Find the Measure of E in an Isosceles Trapezoid? When given the shape of an isosceles trapezoid, finding the measure of the angle ‘e’ is a relatively simple process. In order to find the measure of the angle ‘e’, you need to first identify the sides of the trapezoid. Once you have identified the sides, you need to measure the angles of the trapezoid with a protractor. The angle ‘e’ is the angle formed by the two non-parallel sides of the trapezoid.

The measure of the angle ‘e’ is equal to the sum of the two angles on either side of it. For example, if the two angles on either side of the angle ‘e’ measure 30° and 40°, then the measure of the angle ‘e’ would be 70°. You can also use the formula ‘e = a + b’, where ‘a’ and ‘b’ are the two angles on either side of the angle ‘e’.

## Other Facts about Isosceles Trapezoids An isosceles trapezoid has two pairs of sides that are equal in length. It also has two pairs of angles that are equal in measure. This makes it a symmetrical shape. Furthermore, an isosceles trapezoid has two diagonals, which are the lines connecting opposite corners. The length of the diagonals is equal to the sum of the lengths of the two non-parallel sides. The area of an isosceles trapezoid can be calculated using the formula ‘A = 1/2 (b1 + b2)h’, where ‘b1’ and ‘b2’ are the lengths of the two non-parallel sides and ‘h’ is the height of the trapezoid.
