The vertex angle of an isosceles triangle is 110 degrees. What are the measures of the base angles?
choose the correct answer
30 and 40 degrees.
35 and 35 degrees.
55 and 55 degrees.
60 and 10 degrees.
The measure of each base angle in an isosceles triangle is always equal. Therefore, if the vertex angle is 110 degrees, the measure of each base angle is (180 - 110) / 2 = 35 degrees.
Thus, the correct answer is:
35 and 35 degrees.
