Chapter 4: Similar Shapes

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