In isosceles trapezoid

To Find:
The measure of the angles in the trapezoid
Properties Used:
1. In an isosceles trapezoid, the two base angles are congruent.
2. Diagonals of an isosceles trapezoid are congruent.
3. Each pairs of leg angles of an isosceles trapezoid are supplementary.
Definition:
A trapezoid is a quadrilateral with exactly two parallel sides.
Calculation:
It is given that
Therefore, the lines
By the property of an isosceles trapezoid, that is â€˜base angles are congruentâ€™
