Similar Figures

Front

What are similar figures?

Back

Similar figures are shapes that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

Front

What are congruent figures?

Back

Congruent figures are shapes that are identical in shape and size. Their corresponding sides and angles are equal.

Front

What is the difference between similar and congruent figures?

Back

Similar figures have the same shape but different sizes, while congruent figures are the same shape and size.

Front

What are corresponding sides?

Back

Corresponding sides are the sides of similar or congruent figures that are in the same relative position.

Front

What are corresponding angles?

Back

Corresponding angles are the angles in similar or congruent figures that are in the same relative position.

Front

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

Back

If two triangles are similar, their corresponding angles are equal.

Front

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

Back

If two triangles are similar, the lengths of their corresponding sides are in proportion.

Front

How can you determine if two figures are similar?

Back

To determine if two figures are similar, check if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What is a scale factor in similar figures?

Back

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

Front

If the scale factor of two similar figures is 2:3, what does this mean?

Back

This means that for every 2 units in one figure, there are 3 units in the corresponding side of the other figure.
