ANNOUNCEMENTS Online Assignment 9-1 due tonight! Test re-takes due by Friday!

ARE THE TRIANGLES BELOW SIMILAR? Let’s explore using our TI Calculators!!

AA SIMILARITY If 2 angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

SSS SIMILARITY If the corresponding sides of two triangles are proportional, then the triangles are similar

SAS SIMILARITY If an angle of one triangle is congruent to an angle of a second triangle, and the sides that include the two angles are proportional, then the triangles are similar.
