### Let’s Begin…

Watch the Polygon Clip. Rule up a T-chart and record useful information.

Regular polygons are closed.

Polygons mean many angles.

Have straight lines.

Have same length and angles.

Irregular polygons have a curved line.

Irregular polygons are not closed.

Does not have the same length and angles.

The difference between a regular polygon and an irregular polygon is the length because a regular polygon has the same length an irregular polygon doesn't have the same length .

Regular polygons have same length for each side on the shape, a polygon is a closed figure so it does not have any gaps,polygons have line segments to join up the shape, it is called polygon because poly=many and gon=angles, many angles. Irregular polygons have gaps and do not connect with line segments, they have different angles and different sides and irregular polygons have curved line compared to the straight lines regular polygons gave. That's the difference.

Regular polygons have sides that are the same length, have angles that are the same measures.

Irregular polygons have sides that are different lengths, have angles that are different measures.

All polygons don't have gaps. Regular polygons have angles the same length. Polygon is a Greek word for many angles. Irregular polygons have sides but they are all different lengths.

Regular polygons Connor

A polygon is a closed figure made by joining line segments.

Polygons only have straight lines.

Polygons do have joining.

Polygons have lines that are the same length.

Irregular polygons

Irregular polygons have curved lines.

Irregular polygons don't have joining points.

Irregular polygons have sides that are different lengths.

Polygons have straight lines.

Irregular polygons can have different lines and different angles.
