Explore the similarity of two triangles that have 2 sets of congruent corresponding angles.
You can adjust the size of each set of congruent angles with the sliders.
You can adjust the lengths of AB and DE by dragging the endpoints.
You can move the triangles by sliding the segments AB and DE.

Compare the Similarity Ratios for the sets of corresponding sides.
Which can you conclude?
A. The two triangles are never congruent because the corresponding sides are not proportional.
B. The two triangles are always congruent because the corresponding angles are congruent.
C. The triangles are never similar because the corresponding sides are not congruent.
D. The triangles are always similar because the corresponding sides are proportional.
E. The triangles are never similar because the corresponding sides are not congruent.
F. There is not enough information to tell.
