Classify a polygon as concave, convex, regular or irregular ex 1

The video tutorial explains how to classify polygons as convex, concave, regular, or irregular. It describes the method of extending lines to determine if a polygon is convex or concave. If any extended lines intersect inside the polygon, it is convex. The tutorial also covers how to identify regular polygons, which have congruent sides and angles. If a polygon's angles are not equal, it is irregular. The video concludes with a summary of these classification methods.

How can you determine if a polygon is convex?

• By counting the number of sides

• By measuring all angles

• By extending lines and checking for intersections inside the polygon

• By checking if all sides are equal

What happens if the extended lines of a polygon intersect inside the shape?

• The polygon is concave

• The polygon is convex

• The polygon is regular

• The polygon is irregular

What defines a regular polygon?

• It has more than four sides

• All sides are equal, but angles can vary

• Both sides and angles are equal

• All angles are equal, but sides can vary

Why is a polygon classified as convex irregular?

• It has more than four sides

• All sides are equal, but angles are not

• Both sides and angles are equal

• All angles are equal, but sides are not

Which of the following is true for a convex irregular polygon?

• All sides and angles are equal

• All sides are equal, but angles are not

• All angles are equal, but sides are not

• It has more than four sides
