One of the corners of an isosceles triangle is 108 degrees. Find one of its other corners.

Solution of the task:
In the condition of the task, an isosceles triangle is given, that is, a triangle with two sides equal. We know that there are equal angles opposite to equal sides. What is one angle of the triangle is known from the problem statement. The sum of all three angles of a triangle is 180 degrees.
1. Find what is the sum of the other two angles of the triangle.
180-108 = 72 degrees.
2. Find what one angle of two angles is equal to.
72/2 = 36 degrees.
Answer: One of the angles of an isosceles triangle is 36 degrees.
