If two angles of a triangle are congruent, then the sides opposite those angles are congruent by the converse to the isosceles triangle theorem.
This statement is true.
An isosceles triangle has two congruent sides and two congruent angles.
The converse of the base angles theorem, states that if two angles of a triangle are congruent, then sides opposite to those angles are also congruent.
parallelogram formula is b*h because u can just move a part of the triangle to make it become a rectangle or square. so square/rectangle's formula is the exactly same.
