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 […]

Diagonals of Parallelogram Bisect Each Other

In ┬áthis post, we show that the diagonals of a parallelogram bisect each other. We will use the fact that the diagonal of a parallelogram is a transversal to the opposite sides of the parallelogram. The transversal and the sides form congruent alternate interior angles. Recall that the alternate interior angles formed by a transversal […]
