6. Try again. We know that the triangles share a side so one side is congruent, but we can’t determine if either of the other sides are congruent. Try Again. Although all three angles are congruent, AAA doesn’t not prove triangle congruency. YES! Since these triangles share a side, we can say that those two sides are congruent. Triangle Congruence Review The two triangles below are congruent. Select the congruence shortcut that proves it. SSS ASA SAS AAA

7. Try again. We can determine one set of angles that are congruent (Vertical Angles), but we cannot determine if any other set of angles Are congruent. Try again. We cannot determine if the 3 rd sides of the triangles are congruent with the information that is given. Try Again. There are two sets of sides and one set of angles that are congruent, but the angle is IN BETWEEN the sides. YES! The vertex that the two triangles share creates vertical angles. Vertical angles are congruent angles. Triangle Congruence Review The two triangles below are congruent. Select the congruence shortcut that proves it. SSSSAS ASASSA

8. Try again. We know that one set of the sides in the triangles are congruent, but we cannot determine if either of the other sides are congruent. Try Again. Although all three angles are congruent, AAA doesn’t not prove triangle congruency. YES! Because the two horizontal lines are parallel we know that the sets of base angles are congruent by Alternate Interior Angles. Triangle Congruence Review The two triangles below are congruent. Select the congruence shortcut that proves it. *The horizontal lines are parallel* SSS ASA SAS AAA
