Question

prove that the bisectors of the base angles of an isosceles triangle terminated by the opposite sides are equal .

Answer 1

Here ABC is an isocelous triangle with angle A= angle BMC and NB are the angle bisectorsSo now we observe triangle (MBC) and triangle(NBC)
1) BC = BC2) ang(MBC) = ang(NCB)3) ang(NBC) = ang(MCB)
so by ASA congruency condition the triangles are congruentand henceBN = CM

Answer 2

Step-by-step explanation:

prove prove that the bisector of the base angles of an isosceles triangle are equal
