Question

what is the measure of the vertex angle of an isosceles triangle if one of the base angles measures 48 degrees?
a. 84
b. 96
c. 66
d. 132

Answer 1

In an isosceles triangle, the two base angles have the same measurement. And the sum of all angles in a triangle = 180.

Answer 2

you should be able to figure it out from that

Answer 3

um B might be it...Best Answer - Chosen by Asker
The base angles of any isosceles triangle will always be congruent, so the vertex angle will be:
180 - 2(base angle)
B
