For Congruence, we had 5 shortcuts:

For Similarity, we have 3 shortcuts:

​AA (Angle-Angle) Similarity

​If two angles in one triangle are congruent to two angles in another triangle, then the triangles are similar.

Things to Remember!!

Vertical Angles

1) ​Congruent

2) Formed by any pair of intersecting lines​

3) Share only one point, the vertex​

Things to Remember!!

The sum of all the interior angles of a triangle will always be 180.​

Triangle Angle Sum Theorem

Things to Remember!!

1) Two or more parallel lines intersected by the same transversal create special angle pairs

2) Usually use corresponding and alternating interior angles​

Transversals and Parallel Lines

​If QD is the transversal, then angles Q and D are alternating interior angles.

​If BD is the transversal, then angles BLM and BDC are corresponding angles.

Now we're going to practice using the AA shortcut.
