Triangle ABC is an isosceles triangle (because two sides are equal)

vishweshshrimali5 · Answer

AC = BC (-/- symbol means equal in length/measure)

vishweshshrimali5 · Answer

@mari_catlawd Any doubt till this step ?

vishweshshrimali5 · Answer

Now:

`Pair of angles opposite to the pair of equal sides are also equal`

vishweshshrimali5 · Answer

Thus:

Angle opposite to AC = Angle opposite to BC

vishweshshrimali5 · Answer

Now can you figure out these angles ?
