01:48. Video Transcript. These shapes are all different, but they are all polygons. Polygon party. Only 2D shapes with straight sides are invited to the polygon party. Quadrilaterals have...
Learn what a polygon is, how to classify it by sides and angles, and how to find its properties. Explore the types of polygons with examples, formulas, and practice problems.
- A diagonal of a polygon is a line segment connecting two non-consecutive vertices (corners).
- A Regular polygon has all sides of equal length and each angle also measures equal.
- Polygon is a closed shape made up of straight-line segments. The circle is a closed figure but it is made of a curve. So, a circle is not a polygon.
- A polygon must have a minimum of three sides.
- No, polygons have the same number of sides and angles because they are closed figures with non-intersecting lines.
