Similar Polygons

• Figures that have the same shape but not

  necessarily the same size.

• Figures with corresponding angles that are

  congruent and corresponding side lengths

  that are proportional.

• The ratio of corresponding linear

  measurements of two similar figures.

• A drawing where all lengths are proportional

  to their corresponding actual lengths.
