Sample problems

Two triangles are congruent when their matching sides and angles are equal. The shortcuts are SSS, SAS, ASA, AAS, and (for right triangles) HL. Tick marks show equal sides and arcs show equal angles. Once triangles are congruent, every pair of matching parts is equal (CPCTC: Corresponding Parts of Congruent Triangles are Congruent).

1. In triangles $A B C$ and $D E F$ , angle $A$ = angle $D$ , $A B = D E$ , and angle $B$ = angle $E$ . The equal side lies between the two equal angles. Which congruence shortcut proves the triangles congruent?
2. In triangles $J K L$ and $M N P$ , $J K = M N$ , $K L = N P$ , and $J L = M P$ . Which shortcut proves them congruent?
3. Name the congruence shortcut shown by the marked triangles, where the marked angle sits between the two marked sides.
4. Name the congruence shortcut shown by the two marked right triangles.
