Interior and Exterior Angles of Hexagons

The video tutorial explains how to calculate the interior and exterior angles of a regular hexagon. It outlines a three-step process to find the interior angles by dividing the hexagon into triangles and using the sum of angles in a triangle. The tutorial also covers how to calculate the exterior angle by subtracting the interior angle from 180 degrees. A practice question is provided to reinforce the concepts.

What is the definition of an interior angle in a polygon?

• An angle formed by the intersection of diagonals.

• An angle formed by two adjacent sides of a polygon.

• An angle formed outside the polygon.

• An angle formed by extending one side of the polygon.

What is the first step in finding the interior angle of a regular hexagon?

• Divide the hexagon into squares.

• Measure the exterior angle.

• Pick a vertex and connect it to all other vertices.

• Calculate the sum of all angles.
