Similarity Practice

Front

What is the definition of similar figures?

Back

Similar figures are shapes that have the same shape but not necessarily the same size. Their corresponding angles are equal, and their corresponding sides are in proportion.

Front

What does the symbol '∼' indicate in geometry?

Back

The symbol '∼' indicates that two figures are similar.

Front

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

Back

The corresponding angles of similar triangles are equal.

Front

If triangles ΔABC ∼ ΔDEF, what can be said about the sides?

Back

Front

What is a similarity statement?

Back

A similarity statement expresses that two figures are similar, such as ΔABC ∼ ΔDEF.

Front

True or False: Similar figures must be the same size.

Back

False. Similar figures have the same shape but can be different sizes.

Front

What is the relationship between the sides of similar trapezoids?

Back

The ratios of the lengths of corresponding sides of similar trapezoids are equal.

Front

If trapezoids ABCD and ABQP are similar, what can be said about the ratio of their corresponding sides?

Back

Front

What is the similarity ratio?

Back

The similarity ratio is the ratio of the lengths of corresponding sides of two similar figures.

Front

How do you determine if two triangles are similar using the AA criterion?

Back

If two angles of one triangle are equal to two angles of another triangle, the triangles are similar (AA criterion).
