Similar and Congruent Figures Practice 2

Front

What is the definition of similar figures?

Back

Similar figures must have the same shape but not necessarily the same size.

Front

What is the relationship between the angles of similar figures?

Back

All corresponding angles in similar figures are congruent.

Front

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

Back

The lengths of their corresponding sides are in proportion.

Front

What does the term 'congruent' mean in geometry?

Back

Congruent figures have the same shape and size.

Front

How do you find a missing length in a proportion?

Back

Cross-multiply and solve for the missing length.

Front

If CB / DM = AC / ?, what is the missing length if the answer is AD?

Back

AD is the missing length.

Front

What is the scale factor in similar figures?

Back

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

Front

If a rectangular garden is 45 ft wide and 70 ft long, what is the length on a blueprint if the width is 9 in?

Back

The length on the blueprint is 14 in.

Front

What is the significance of the Side Angle Side (SAS) criterion?

Back

SAS can be used to prove that two triangles are congruent.

Front

What does it mean for two figures to be proportional?

Back

Two figures are proportional if their corresponding sides are in the same ratio.
