Look at the similar shapes shown below.

1. What is the scale factor from shape A to shape B?

What is the factor between $48$ and $8$?

Multiply by $6$.

2. Find the lengths of the missing sides.

Multiply each side from shape A by the scale factor to get the new sides for shape B.

3. Sketch a new shape C that is similar to shape A and has a scale factor of $1$. What do you know about the measures of the angles and sides on this new shape? Label them on your picture.

4. When two shapes are similar and have a scale factor of one, what are they called?
