  2. Postulate 25:Angle-Angle (AA) Similarity Postulate If two angles of one triangle are congruent to two angles of another triangle, then the two triangles are similar. Image taken from: Geometry. McDougal Littell: Boston, 2007. P. 381.

  3. Ex. 1: Determine whether the triangles are similar. If they are, write a similarity statement. Explain your reasoning. Image taken from: Geometry. McDougal Littell: Boston, 2007. P. 382.
