Side-side-side | if all 3 sides of a triangle are congruent. |
Side-Angle-Side | if two sides and 1 angle are congruent in a triangle. |
angle- side-angle | if two angles and 1 side are congruent in a triangle. |
triangle sum theorem | the sum of the measured of the interior angles if a triangle. |
exterior angle theorem | the measure of an exterior angle is equal to the sum of the measures of the nonadjacent angles. |
hypotenuse leg | the hypotenuse and a leg of a right triangle are congruent to the other leg, then the two triangles are congruent. |
Angle-Angle-Side | if two angles and a non-included side of one triangle are congruent to two angles, then the two triangles are congruent. |
base angles | if two sides of a triangle are congruent, then the two angles opposite them are congruent. |
converse of the base angles theorem | if two angles of a triangle are congruent, them to angles opposite them are congruent. |
