• The two triangles have two angles congruent (equal) and the included side between those angles congruent. This forces the remaining angle on our C A T to be: 180 ° - ∠ C - ∠ A. This is because interior angles of triangles add to 180 °. You can only make one triangle (or its reflection) with given sides and angles.
• Study Guide and Intervention (continued) Congruent Triangles 4-3 Example Prove Triangles Congruent Two triangles are congruent if and only if their corresponding parts are congruent. Corresponding parts include corresponding angles and corresponding sides. The phrase "if and only if" means that both the conditional and its converse are true.
• In right triangles, if two legs are congruent and if the two hypotenuses are congruent, then the triangles are congruent. This is known as the hypotenuse leg theorem. Note that this is the SSA shortcut which does not apply to non-right triangles. Applying the Pythagorean Theorem shows that only one value is possible for the other leg.
• SR SP SP + PR SP 4 + 12 4 = = = 16 4 = 4. ST SQ SQ + QT SQ 5 + 15 5 = = = 20 5 = 4. So, the side lengths SR and ST are proportional to the corresponding side lengths of ∆PSQ. Because S is the included angle in both triangles, use the SAS Similarity Theorem to conclude that ∆RST ~ ∆PSQ.

• 7. 4 Congruent Triangles A Solidify Understanding Task We know that two triangles are congruent if all pairs of corresponding sides are congruent and all pairs of corresponding angles are congruent. We may wonder if knowing less information about the triangles would still guarantee they are congruent.

• Two triangles are congruent if and only if their corresponding parts are _____. ! CPCTC – Corresponding parts of congruent triangles are congruent Example #1: In the following figure, QR = 12, RS = 23, QS = 24, RT = 12, 14 TV = 24, and RV = 23.
Handicraft charm 4Label the incenter, I as the intersection of BE and FC. It is where the angle bisectors meet. Then by theorem, FI and IE are congruent and IB and IC are congruent, since they are equal distances to the sides of the triangles from the incenter. FI = IE and IB = IC. FC = FI + IC = EI + IB = EB = n <---- let the measure of this side by n.

Thus, two triangles with the same sides will be congruent. (Note: If two triangles have three equal angles, they need not be congruent. All that we know is these triangles are similar.) SAS: "Side, Angle, Side". It is a specific scenario to solve a triangle when we are given 2 sides of a triangle and an angle in between them.
