Tell whether the two figures are similar. Explain your reasoning.

• Yes, similar because they are the same shape and side lengths are proportional.

• No, not similar because they are the same shape, but side lengths are not proportional.

• Yes, same shape

• No, different sizes

What are similar shapes?

• Are shapes that have the same shape, but not necessarily the same size.

• Compares the sizes of the parts of the scale drawing to the actual sizes on the original object.

• They are sides that are in the same position in different plane figures. 

• They are sides that have different ratios.

What is a scale factor?

• Shapes that have the same shape, but not necessarily the same size.

• A ratio/number that compares the sizes of the parts of the scale drawings.

• They are sides that are in the same position in different plane figures.
