Similar and Congruent

Front

What are similar figures?

Back

Figures that have the same shape but may have different sizes. Their corresponding angles are equal and their corresponding sides are in proportion.

Front

What does it mean for angles to be congruent?

Back

Angles that have the same measure.

Front

Are all corresponding angles in similar figures congruent?

Back

Yes, all corresponding angles in similar figures are congruent.

Front

What is the relationship between corresponding sides of similar figures?

Back

The lengths of corresponding sides are in proportion.

Front

What does it mean for two figures to be congruent?

Back

Two figures that are the same shape and size.

Front

If two triangles are similar, what can we say about their angles?

Back

All corresponding angles are equal.

Front

If line CB corresponds to line GF, what can we say about their lengths?

Back

The lengths of line CB and line GF are in proportion to the lengths of their corresponding sides.

Front

Which of these figures are similar: QRST and WXYZ, ABCD and QRST, WXYZ and ABCD?

Back

ABCD is similar to QRST.

Front

How can you determine if two figures are similar?

Back

By checking if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What is the significance of corresponding lines in similar figures?

Back

Corresponding lines help identify which sides and angles are related in similar figures.
