The point that is in purple can be moved to change the measurement of the angles in both figures.
Move the triangles around. What do you notices about the two triangles?
Are there any cases where two sets corresponding angles are congruent and one set of corresponding sides is congruent but the triangles are not congruent?
How is ASA different from AAS?
Explore the applet above [move the bright green point around to change the triangles. Note, two sides and a non-included angle are congruent] - remember that SSA is not a shortcut to triangle congruence. Is there ever a case when it works?
