1. | Some more Criteria for Congruence of Triangles | Theorem 7.4 Theorem 7.5 |
- Some more Criteria for Congruence of Triangles
Theorem 7.4 - (SSS congruence rule) : If three sides of one triangle are equal to the three sides of another triangle, then the two triangles are congruent.
Theorem 7.5 - (RHS congruence rule) : If in two right triangles the hypotenuse and one side of one triangle are equal to the hypotenuse and one side of the other triangle, then the two triangles are congruent. RHS stands for Right angle - Hypotenuse - Side
