How do you determine if polygons are similar?

• What relationships are formed by corresponding angles of similar polygons?

• What relationships are formed by corresponding sides of similar polygons?

• How do you determine if two triangles are similar?

a) corresponding angles of similar polygons are congruent

b) corresponding sides of similar polygons are proportional

c) a triangle is a polygon

Step-by-step explanation:

By definition, similar polygons have congruent corresponding angles and proportional corresponding sides.

A triangle is a polygon, so two triangles will be similar if they have congruent corresponding angles and proportional corresponding sides.

___

For an n-sided polygon, one only needs to show the conditions are met for n-1 angles and sides. Those will determine the measures of the final angle/side.
