Since the sum of the angles in a triangle is 180°, then the two base angles sum to (180° - 38° = 142°). In isosceles, these two angles are equal, so each one is:

  • 142° / 2 = 71°

The isosceles trapezoid is part of an isosceles triangle with a 32 degrees vertex anglewhat is the measure of an acute base angle of the trapezoid?

In an isosceles triangle with a vertex angle of 32 degrees, the base angles are each equal to ( \frac{180^\circ - 32^\circ}{2} = 74^\circ ). Since the isosceles trapezoid is formed from this triangle, the acute base angles of the trapezoid are also equal to the base angles of the triangle. Therefore, the measure of an acute base angle of the trapezoid is 74 degrees.


What is the measure of an acute base angle of the trapezoid of an isosceles triangle vertex of 46 degrees?

For an isosceles triangle with vertex 46 degrees, the sum of the remaining two base angles is 180-46 = 134 degrees. Base angles are equal because it's isosceles, so each angle is half of their sum. 134/2 = 67 degrees. Thus, any isosceles trapezoid formed inside that isosceles triangle by drawing parallel lines to the triangle's base, will have base angle measures of 67 degrees, which are triangle's base angles.
