Front

What is the definition of similar triangles?

Back

Triangles that have the same shape but not necessarily the same size; their corresponding angles are equal and their corresponding sides are proportional.

Front

If two triangles are similar, what can be said about their corresponding angles?

Back

Their corresponding angles are congruent.

Front

If triangle A is similar to triangle B, and the length of a side in triangle A is 5, what is the length of the corresponding side in triangle B if the ratio of similarity is 2:1?

Back

10

Front

What is the AA criterion for triangle similarity?

Back

If two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

If triangle A has sides 2, 3, 4 and triangle B has sides 4, 6, 8, are they similar?

Back

Yes, because the sides are proportional.
