Question

The two triangles below are similar.

What is the ratio of the corresponding side lengths?
4:9
4:2
26:26
4.5:2

Answer 1

4:2

Explanation:

To find the ratio of similar triangles, write a ratio between corresponding sides. Corresponding sides are sides which are matching in place and orientation between triangles. Write the ratio as
`(big triangle)/(small triangle)`.

The side lengths 4 and 2 are corresponding sides. The side lengths 9 and 4.5 are corresponding sides.

The ratios are
`(9)/(4.5)` and
`(4)/(2)`. These can also be written as 4:2 and 9:4.5
