Similar Figures & Scale Drawings

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 is a scale drawing?

Back

A scale drawing is a representation of an object or area that is drawn to a specific ratio or scale, allowing it to be larger or smaller than the actual size.

Front

What are corresponding sides?

Back

Corresponding sides are the sides of similar figures that are in the same relative position. They are proportional in length.

How do you find the height of a tree using similar figures?

Back

You can use the ratio of the heights of two similar figures to find the unknown height by setting up a proportion.

Front

If two figures are similar, what can you say about their angles?

Back

The corresponding angles of similar figures are equal.

Front

What is the scale of a drawing?

Back

The scale of a drawing is the ratio of a distance on the drawing to the corresponding distance in real life.

Front

How do you calculate the width of a parking lot in a scale drawing?

Back

To find the width in a scale drawing, multiply the real-life width by the scale factor.

Front

What is the relationship between the sides of similar figures?

Back

The lengths of corresponding sides of similar figures are proportional.

Front

What does it mean if two shapes are congruent?

Back

Congruent shapes are identical in shape and size, meaning all corresponding sides and angles are equal.

Front

How do you solve for a missing side in similar figures?

Back

Set up a proportion using the lengths of the corresponding sides of the similar figures and solve for the unknown.
