| 1) What is the smaller angle of the isosceles trapezoid?

In an isosceles trapezoid, the angles at the bases are equal, therefore, to find a smaller angle, you need to divide the sum of the two angles of this trapezoid in half, that is, 102˚: 2 = 51˚.

2) What is the degree measure of the greater angle of the isosceles trapezoid?

180˚ – 51˚ = 129˚.

Answer: the greater angle of the isosceles trapezoid is 129˚.
