Front

Are the two triangles similar?

Back

Yes

Front

What is the ratio of the sides of two similar triangles?

Back

Front

If Triangle A has sides of 3 cm, 4 cm, and 5 cm, and Triangle B has sides of 6 cm, 8 cm, and 10 cm, are they similar?

Back

Yes, they are similar because the sides are in proportion.

Front

What is the Angle-Angle (AA) criterion for similarity?

Back

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

Front
