I need help on these 2 proofs.

1. Prove that if all sides and angles of a triangle are congruent, then the triangle is equilateral.

2. Prove that if 2 sides and angles of a triangle are congruent then the triangle is isosceles.

The proof of (1) follows DIRECTLY from the definition of an equilateral triangle. I suggest you study that definition.

The proof of (2) follows DIRECTLY from the definition of an isosceles triangle. Study that definition, too.
