The Isosceles Triangle Theorem:If two sides of a triangle are congruent, then the angles opposite the sides are congruent.The Converse of Isosceles Triangle Theorem:If two angles of a triangle are congruent, then the sides opposite those angles are congruent.
The isosceles triangle theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent.
Correct as would be the case for an isosceles triangle or an equilateral triangle
2 congruent sides and the opposite angles of the sides are also congruent. There is only 1 line of symmetry.
The isosceles triangle theorem states that if two sides of a triangle are congruent, the angles opposite of them are congruent. The converse of this theorem states that if two angles of a triangle are congruent, the sides that are opposite of them are congruent.
