Which angle corresponds to Angle CBA in scaled copies?

Back

Angle CBA corresponds to Angle RQP.

Front

If the length of a side in a small triangle is missing, how do you find it?

Back

You can find the missing side length by using the scale factor and the lengths of corresponding sides.

How do you determine the scale factor between two similar shapes?

Back

The scale factor is determined by dividing the length of a side of one shape by the length of the corresponding side of the other shape.
