Classifying a polygon in two different ways ex 4

The video tutorial explains how to classify polygons as concave or convex and regular or irregular. It begins by describing how to identify concave polygons by extending their sides and checking for intersections within the polygon's interior. The tutorial then differentiates between regular and irregular polygons, emphasizing that regular polygons have equal sides and angles, while irregular ones do not. The video concludes with a summary of the classification process.

What characteristic defines a concave polygon?

• All sides are equal

• All angles are equal

• Extending sides intersect the interior

• It has more than four sides

How can you determine if a polygon is convex?

• All sides are equal

• It is a quadrilateral

• It has at least one right angle

• No extended sides intersect the interior

What makes a polygon regular?

• All sides and angles are equal

• All sides are different

• It has at least one right angle

• It is a quadrilateral

Which of the following is true for an irregular polygon?

• Sides and angles are not all equal

• It is always concave

• All sides are equal

• All angles are equal

What was the final classification of the polygon discussed?

• Convex and irregular

• Concave and regular

• Convex and regular

• Concave and irregular
