Math Makes Sense 6.4 Investigating Polygons Intro

A polygon is:

• a closed shape with straight line segments

• a open shape with straight line segments

• a closed shape with non-straight line segments

• a open shape with non-straight line segments

Are these 3 shapes all polygons?

• Yes

• No

• 2 are, 1 isn't

• 1 is, 2 are not

Are all 3 of these shapes polygons?

• Yes

• No

• 2 are, 1 is not

• 1 is, 2 are not

A regular polygon is:

• a polygon with a job and a family

• not all sides equal

• not all angles equal

• all sides equal and all angles equal

A regular polygon has:

• a job, wife, and kids

• works during the week and has fun on the weekends

• has no lines of symmetry

• has a line of symmetry

This picture shows what?

• 7 lines of symmetry

• only 1 line of symmetry

• no lines of symmetry

• a spider's web
