Question

in the given figure AB and AC of an isosceles triangle ABC are produced to N and M, respectively such that AN=AM. prove that MB=NC​

Answer 1

Step-by-step explanation:

Given- AN=AM

AB=AC. (equal side of isosceles triangle)

To prove=MB=NC

Proof= ∆BAM≈∆CAN. (Congurent)

AB=AC. (stated above)

angle A=Angle A. ( common)

AM = AN. ( Given)

by SAS congurency rule

by CPCT

MB = NC

hence proved
