The video tutorial explains the differences between convex and concave polygons. A convex polygon is defined as a polygon where extended sides do not cross the interior, while a concave polygon has sides that, when extended, do cross the interior. The tutorial uses examples to illustrate these concepts and demonstrates how a convex polygon can be transformed into a concave one by altering the direction of its sides.

What is a key characteristic of a convex polygon?

• It has at least one right angle.

• Extended sides do not cross the interior.

• All sides are equal in length.

• It is always a regular polygon.

How does a concave polygon differ from a convex polygon?

• It has more sides.

• It is a 3-dimensional figure.

• Extended sides cross the interior.

• It is always symmetrical.

What is true about both concave and convex polygons?

• They both have equal angles.

• They are both closed 2-dimensional figures.

• They are both open figures.

• They both have curved sides.

What happens when you extend the sides of a concave polygon?

• They create a new polygon.

• They cross the interior of the polygon.

• They form a circle.

• They remain outside the polygon.

How can a convex polygon be transformed into a concave polygon?

• By adding more angles.

• By increasing the number of sides.

• By changing the direction of some sides inward.

• By making all sides equal.
