N#____ ____/____/____ 4-4 Part1 Proving Triangles Congruent SSS and SAS
The definition of congruent triangles states that you need 6 pairs of congruent corresponding parts to prove triangles congruent. In reality, you only need certain pairs of congruent corresponding parts.
C Y Side-Side-Side Congruence: (SSS) If the sides of 1 triangle are congruent to the sides of another triangle, then the triangles are congruent. A B X Z
P N If the angles of 1 triangle are congruent to the angles of another triangle the triangles are not necessarily congruent. AAA congruence does not guarantee triangle congruence. L Q R M
W Included Angle: The angle formed by 2 sides. <Y is the included angle for WY and XY. X Y
L Q P Side-Angle-Side Congruence (SAS) If 2 sides and the included angle of 1 triangle are congruent to 2 sides and the included angle of another triangle, then the triangles are congruent. M N R
State if the triangles are congruent. If they are state how you know. YES SAS YES SSS NO
