In triangle ABC, which is isosceles, angle A is equal 40 degrees. What are the possible measure of angle B?
Angle B = Angle C = [180 - 40] / 2 =70 degrees.
That is only 1 possibility, another possiblity is angle A=angle C
so angle B=100
Depends on how you draw the triangle.
other possibility as the Guest said B=70
