Objective
• You’ll classify polygons be their sides
Instructions
• Match the polygon with its correct classification.
• Tell whether the polygon is always regular.
Polygons
• A polygon is a closed plane
figure that is formed by
three or more segments
called sides.
• Each side intersects exactly
with two other sides at a
vertex.

Regular Polygons
Regular polygons are polygons with sides of
equal length and angles of equal measure.
Polygons that are not regular are irregular
figures.
Regular Irregular
Classify the polygons as regular or irregular
a) Regular
b) Irregular
a) Regular
b) Irregular
Glossary
• Segment is a part of a line, it has two endpoints.
• •
• Intersects are lines in a plane that meet at a point.
• Vertex – a point at which two sides of a polygon meet.
•
• Angle – A figure formed by two rays with the same
endpoint.
