Defined, the triangle proportionality theorem states that if you draw a line parallel to one of the sides of a triangle that also crosses the other two sides, then that line will divide the two sides in a proportional way.
Triangle Congruence Theorems. 1  There area number of congruence theorems for triangles based on the criterion considered. 2  Two triangles are said to be similar if the three angles of one triangle are congruent to three angles of another. 3  This theorem is commonly known as the mid segment theorem.
