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

What are corresponding sides?

• 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.
