ProofThe Isosceles Triangle Theorem If in ABC we have AB AC

Proof:The Isosceles Triangle Theorem – If in ABC we have AB AC , then B C .

Proof:The Isosceles Triangle Theorem – If in ABC we have AB AC , then B C .

We can apply the SIN rule in a triangle.

We know that c/SINC = b/SINB

So, if c= b, then SINC = SINB

So, taking inverse both the sides

C=B

<Hence Proved>
