Similar Figures Practice

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 the lengths of their corresponding sides are proportional.

Front

What does it mean for two figures to be proportional?

Back

Two figures are proportional if the ratios of their corresponding side lengths are equal.

Front

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

Back

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

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

Solve for p: 5/10 = p/20

Back

p = 10

Front

If triangle ABC is similar to triangle DEF, and the length of side AB is 4 cm and side DE is 8 cm, what is the scale factor?

Back

The scale factor is 2:1.

Front

What is the scale factor?

Back

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

Front

If two similar rectangles have a scale factor of 3:1, and the length of the smaller rectangle is 2 ft, what is the length of the larger rectangle?

Back

The length of the larger rectangle is 6 ft.

Front

Solve for X: 3/4 = X/16

Back

X = 12

Front

What is the relationship between the areas of two similar figures?

Back

The ratio of their areas is equal to the square of the scale factor.
