Front

Matching angles are called

Back

Corresponding Angles

Front

What does it mean for two shapes to be similar?

Back

Same shape, but different size.

Front

Sides in similar figures must be proportional. True or False?

Back

True

Front

Are the triangles similar? (Yes/No)

Back

No

Front

Find the missing side: If one triangle has sides of 3 and 4, and the other has a side of 5, what is the missing side?

Back

7

Front

What is the ratio of the sides of similar triangles?

Back

The ratio of the corresponding sides is constant.

Front

If two triangles have angles of 30°, 60°, and 90°, are they similar?

Back

Yes, they are similar.

Front

What is the Angle-Angle (AA) similarity postulate?

Back

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

Front

Back

The ratio of their areas is 1:4.

Front

What is the definition of similar triangles?

Back
