I WONDER - What Is A Concave Pentagon?

The video tutorial introduces key geometry concepts, focusing on moles, 180-degree angles, and the orientation of vertices pointing inward. It provides a foundational understanding of these elements and their relationships in geometric figures.

What is a key characteristic of moles in geometry?

• They are always circular.

• They have a fixed number of sides.

• They are used to measure angles.

• They have specific properties and significance.

Why is 180 degrees significant in geometry?

• It represents a full circle.

• It is the sum of angles in a triangle.

• It is used to calculate area.

• It is the measure of a straight line.

Which of the following is true about 180 degrees?

• It is the measure of a right angle.

• It is the measure of a reflex angle.

• It is the measure of a straight angle.

• It is the measure of an acute angle.

What happens when vertices point inward?

• The shape is considered concave.

• The shape is a regular polygon.

• The shape becomes a polygon.

• The shape is symmetrical.

In which scenario do vertices point inward?

• In a concave shape.

• In a symmetrical shape.

• In a regular polygon.

• In a convex shape.
