The Right Triangle Leg Leg Congruence Theorem

The Right Triangle Leg Leg Congruence Theorem is a theorem for right triangles that says if the two corresponding shorter legs of two right triangles are congruent, then the two triangles are congruent. For instance, if the length of the shorter legs of the two triangles is 5, and the other leg is 12, then […]

Proving the Perpendicular Bisector Theorem Using SAS Congruence

In the previous post, we have proved the Perpendicular Bisector Theorem using reflection. In this post, we prove the same theorem using SAS Congruence. Theorem If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment.
