Let’s look at irregular polygons Irregular polygons are made up of segments that are not all the same size, so their interior angles will not be equal. However they are still named according to how many sides they have

What’s this?

Quadrilateral

What’s this?

Quadrilateral It’s got four sides, right?

What’s this?

Pentagon

How about these?

Are they polygons? How many segments make up each one?

How about these? hexagon

How about these? hexagon octagon

How about these? hexagon octagon This one is not a polygon! Why not?

What polygons can you find in our classroom?
