In the figure, triangle ABC is an isosceles triangle with AB = AC and measure of angle ABC = 50o. Then the measure of angle BDC and angle BEC will be
40o, 120o
60o, 100o
50o, 100o
80o, 100o
In an isosceles triangle PQR, PQ = PR and angle Q measures 40o then the measure of angle P is:
In an isosceles triangle ABC, AB = AC and angle A measures 700, then the measure of angle B is:
The bisectors of the base angles of an isosceles triangle ABC, with AB = AC, meet at O.
