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 proportional.

Front

What does it mean for sides of similar polygons to be proportional?

Back

It means that the ratios of the lengths of corresponding sides of the polygons are equal.

Front

What are corresponding angles in similar figures?

Back

Corresponding angles are angles in similar figures that are in the same relative position. They are equal in measure.

Front

How do you find the missing side length in similar figures?

Back

To find the missing side length, set up a proportion using the lengths of the corresponding sides of the similar figures.

Front

What is the relationship between the side lengths of similar figures?

Back

The side lengths of similar figures are in proportion to each other.

Front

What is the definition of corresponding sides?

Back

Corresponding sides are sides in two or more 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 congruent.

Front

What is the significance of the scale factor in similar figures?

Back

The scale factor is the ratio of the lengths of corresponding sides of two similar figures, indicating how much one figure is enlarged or reduced compared to the other.

Front

Can two figures be similar if their corresponding angles are not equal?

Back

No, two figures cannot be similar if their corresponding angles are not equal.

Front

What is the formula for finding the scale factor between two similar figures?

Back

The scale factor can be found by dividing the length of a side of one figure by the length of the corresponding side of the other figure.
