- This page is the high school geometry common core curriculum support center for objective G.CO.8 about explaining the criteria for triangle congruence. Many teaching resources such as activities and worksheets are provided here.
- Besides SSS (Side, Side, Side), there are several other ways to show that two triangles are congruent. Let's take a look at more. Method 2: ASA (Angle, Side, Angle) You can also prove that two triangles are congruent by showing that two angles and the included side are congruent. In this example, < R is congruent to < X, < S is congruent to < W and side RS is congruent to side XW.

State the correct postulate to prove that each pair of right triangles in this printable practice set is congruent.

A typical proof using triangle congruence will use three steps to set up the three congruent triangle parts (several may be givens), a fourth step invoking a triangle congruence theorem, followed by a CPCF (Congruent Parts of Congruent Figures are congruent) invocation to relate additional congruent triangle parts. This kind of proof is very ...
