Similar Polygons - Scale Factor - Ratios |
|
|
|
|
Problems in this worksheet require use of the properties of similar polygons. Students must
identify similar polygons, write similarity statements, find ratios and scale factor.
There are also a few problems on golden rectangles, which are rectangles whose side lengths are in the golden ratio --approximately 1:1.618. |

2) Are the polygons similar? If they are, identify the correct similarity statement
and ratio.
3) The polygons below are similar, but not necessarily drawn to scale. Find the
values of x and y.
5) The measures of the corresponding sides of the polygons are proportional. If
AD = 6, DC = 3, and WZ = 33, find YZ. (not drawn to scale)
8) Triangles ABC and DEF are similar figures. Find the lengths of AB and EF. B 4
C A 5x E x F D

11) If one measurement of a golden rectangle is 8.8 inches, which could be the other
measurement?
12) If the long side of a golden rectangle is 21 cm, what is its area? Round your
answer to the nearest tenth.
