In an isosceles trapezoid, the sum of the two angles is 204 °, find the acute angle of the trapezoid.
September 30, 2021
Since the trapezoid is isosceles, 2 obtuse angles are equal and 2 acute angles are equal. We know that the sum of the two angles is 204 °. To find one angle 204 ÷ 2 = 102. We found an obtuse angle (since 102> 90). To find an acute angle, you need to subtract an obtuse angle from 180. Find an acute angle 180 – 102 = 78. The acute angle of a trapezoid is 78 °
