Question

the isoceles triangle theroem says if two sides of a triangle are congruent then the angles opposite of those sides are congruent. if you are using this figure to prove the isoceles triangle theroem, which of the following would be the best strategy?

A draw km so m is the midpoint of jl then prove triangle jkm is congruent to triangle lkm using sas

B draw km bisecting angle k with m on jl then prove triangle jkm is congruent to triangle lkm using asa

C draw km bisecting angle k with m on jl then prove triangle jkm is congruent to triangle lk
using aas

Answer 1

d draw km so that m is the midpoint of jl then prove triangle jkm is congruent to lkm using sss

Answer 2

I wouldn't know to me it is just obvious that they are congruent.

I think it has to do something with midpoints so
