Interior Angles of Polygons

This video tutorial covers the basics of polygons, including their definition, properties, and types such as equilateral, equiangular, and regular polygons. It explains how to identify polygons and calculate the sum of their interior angles using a formula. The tutorial also provides examples of different polygons, their names, and how to solve problems involving polygon angles.

What is a polygon?

• A closed figure with straight sides

• A shape with curved sides

What is a vertex in a polygon?

• The longest side of a polygon

• A curved edge of a polygon

• A point where two sides meet

• A side of the polygon

What does 'equilateral' mean in terms of polygons?

• All angles are equal

• The polygon has no vertices

• The polygon is a triangle
