Question

What is the sum of the interior angles of a isosceles trapezoid?

Answer 1

`360˚`

Explanation:

The sum of the angles in any quadrilateral is `360˚`.

Notice how two triangles can be formed with vertices also at the trapezoid. Each triangle's interior angles have a sum of `180˚`, so since two triangles can be created, the sum of the interior angles is `180˚xx2=360˚`.
