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.
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.
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
In all triangles, the angles always measure up 180 degrees. In an isosceles triangle two of the angles are equal.
An isosceles triangle can be acute, obtuse, or right, depending on the measure of its angles. If all angles are less than 90 degrees, it is an acute isosceles triangle. If one angle is greater than 90 degrees, it is an obtuse isosceles triangle. If one angle is exactly 90 degrees, it is a right isosceles triangle.
A right triangle. Also an isosceles triangle.

It is an isosceles triangle
In all triangles, the angles always measure up 180 degrees. In an isosceles triangle two of the angles are equal.
The three interior angles measure 45, 45 and 90 degrees.
An isosceles triangle can be acute, obtuse, or right, depending on the measure of its angles. If all angles are less than 90 degrees, it is an acute isosceles triangle. If one angle is greater than 90 degrees, it is an obtuse isosceles triangle. If one angle is exactly 90 degrees, it is a right isosceles triangle.
The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.
That's an isosceles triangle.
A right triangle. Also an isosceles triangle.
The isosceles trapezoid will have 2 equal base angles of 50 degrees and 2 other equal angles of 130 degrees.
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
