What is a Polygon?
In this animated video I would like to talk about Polygons
Polygons are 2-dimensional closed shapes.
A closed shape does not have any openings, and all of the lines connect.
You can’t leave the inside of a closed shape without crossing a line.
Polygons have straight lines and do not have curves
A polygon has three parts.
Vertices which are the point at which the lines intercept
Angles are formed by intercepting lines
There are several types of polygons
A regular polygon has equal lines and angles
An irregular does not have equals lines and angles
A concave polygon has one angle greater than 180 degrees
A convex polygon does not have any internal angles greater than 180 degrees
A simple polygon does not have any lines that cross over.
A complex polygon has at least one line that crosses over itself
Named after the number of sides and angles
Triangle 3 sides
After 12 sides it is acceptable to give the number of sides and then gon
For example 14 gon has 14 sides
