  1. 2. The Angle-Side-Angle (ASA) Congruence Theorem states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.
  2. 4. If an isosceles triangle has exactly two congruent sides, the base angles are the two angles that have the base as a side.
  3. 7. The Hypotenuse-Leg (HL) Congruence Theorem states that if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent.
  4. 8. If an isosceles triangle has exactly two congruent sides, the base is the side opposite the vertex angle.
  5. 9. states that if a triangle is equiangular, then it is equilateral.

  1. 1. states that if a triangle is equilateral, then it is equiangular.
  2. 3. The Angle-Angle-Side (AAS) Congruence Theorem states that if two angles and a nonincluded side of one triangle are congruent to the corresponding two angles and nonincluded side of another triangle, then the triangles are congruent.
  3. 5. If an isosceles triangle has exactly two congruent sides, the congruent sides are the legs.
  4. 6. If an isosceles triangle has exactly two congruent sides the vertex angle is the angle formed by the legs.
