Determine if a polygon is concave or convex ex 2

The video tutorial explains how to classify polygons as regular or irregular and convex or concave. It highlights that a regular polygon has all sides and angles equal. To determine if a polygon is convex, extend its sides to see if any intersect the interior. If none do, the polygon is convex. The tutorial concludes by summarizing the classification process.

What is a key characteristic of a regular polygon?

• It has at least one right angle.

• All sides and angles are equal.

• All angles are different.

• All sides are different lengths.

How can you determine if a polygon is convex?

• By measuring the angles to see if they are all acute.

• By extending the sides and seeing if they intersect the interior.

• By checking if any sides are curved.

• By counting the number of sides.

What happens if the extended sides of a polygon intersect the interior?

• The polygon is regular.

• The polygon is concave.

• The polygon is irregular.

• The polygon is convex.

Which of the following is true for a convex polygon?

• It is always a triangle.

• It has sides of varying lengths.

• All extended sides remain outside the polygon.

• It has at least one angle greater than 180 degrees.

What is the final classification of the polygon discussed in the video?

• Convex and irregular

• Concave and regular

• Concave and irregular

• Convex and regular
