Polygons are similar when they have equal corresponding angles and proportional corresponding sides. Two polygons are given as examples of similar polygons - a triangle and a square. The document then provides examples of similar and non-similar polygons and asks the reader to identify which are similar by setting up proportions of corresponding sides and finding missing side lengths. The reader is directed to read specific pages and complete selected questions.

1. Similar Polygons

2. Some types of polygons

3. A polygon is a shape that has any
number of straight sides connected at
vertices(corners).
A triangle is a 3 sided polygon.
A square is a 4 sided polygon.

4. Polygons are similar when...
Two polygons have equal
corresponding angles
and
The corresponding sides are proportional
We have already studied a special case
of similar polygons
Similar triangles
