Front

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

Back

The ratios of their corresponding sides are equal.

Front

What is the relationship between corresponding angles in similar figures?

Back

Corresponding angles are equal.

Front

If triangle ABC is similar to triangle DEF, and the length of side AB is 10 cm and side DE is 15 cm, what is the ratio of similarity?

Back

The ratio of similarity is 10:15 or 2:3.

Front

A triangle has sides measuring 5 cm, 12 cm, and 13 cm. A similar triangle has a side measuring 10 cm. What is the length of the other sides?

Back

The other sides are 24 cm and 26 cm.

Front

What is a proportion in the context of similar figures?

Back

A proportion is an equation that states that two ratios are equal.

Front

If two triangles are similar, how do you find a missing side length?

Back

Use the ratio of the corresponding sides to set up a proportion.

Front

In similar figures, if one side of a triangle is 8 cm and the corresponding side in another triangle is 12 cm, what is the scale factor?

Back

The scale factor is 8:12 or 2:3.

Front

What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but not necessarily the same size.

Front

If triangle XYZ is similar to triangle PQR, and the length of side XY is 6 cm and side PQ is 9 cm, what is the length of side YZ if side QR is 12 cm?

Back
