Front

If two figures are similar, what can we say about their shapes?

Back

Front

If the lengths of two similar figures are in the ratio 2:5, what is the ratio of their areas?

Back

The ratio of their areas is 4:25.

Front

What is the definition of similar figures?

Back

Similar figures are figures that have the same shape but may differ in size.

Front

If one triangle has sides of 3, 4, and 5, and another triangle is similar with the longest side of 10, what are the lengths of the other two sides?

Back

Front

If two similar rectangles have a length ratio of 3:4, what is the ratio of their widths?

Back

The ratio of their widths is also 3:4.

Front

How do you find a missing side in similar figures?

Back

Use the proportion of the corresponding sides to set up a ratio and solve for the missing side.

Front

If triangle A has sides of 6, 8, and 10, and triangle B is similar with the shortest side of 3, what is the length of the longest side of triangle B?

Back
