A detailed tutorial on how to identify hexagons. Step by step tutorial including several examples of identifying hexagons for reference.
Overview
A hexagon is any polygon that has six sides. Hexagons can either be regular or irregular. Regular hexagons are close to the shape of a circle with 6 straight edges. Irregular hexagons are any other shape that has six sides, provided that it is still considered a polygon.

A detailed tutorial on how to identify pentagons. Step by step tutorial including several examples of identifying pentagons for reference.
Overview
A pentagon is any polygon that has five sides. Pentagons can either be regular or irregular. Regular pentagons are close to the shape of a house. Irregular pentagons are any other shape that has five sides, provided that it is still considered a polygon.
Description
A detailed tutorial on the main diagonal of a matrix. Step by step tutorial including several examples of main diagonals for reference.
Overview
The main diagonal of a matrix is the diagonal that starts at the top left corner, and continues down and to the right one step until either the other corner is reached (square matrices only), the bottom of the matrix is reached, or the right side of the matrix is reached. The main diagonal is also sometimes called the primary diagonal or the leading diagonal
Description
This video shows pictures of different types of polygons, and labels them as either regular or irregular. It gives the different traits of both regular polygons and irregular polygons, and shows how and why they are different. It also identifies what a polygon is. Many different examples are provided in the video.
Overview
Polygon is probably a term you\’ve heard before. It refers to a shape – actually, it refers to many different shapes. A polygon is a shape that consists of at least three straight lines that connect to form either a regular or an irregular shape. We have all seen polygons before – Squares and triangles are both polygons. So are pentagons (a 5-sided figure), hexagons (a 6-sided figure), and octagons (an 8-sided figure). Any of these that have sides of the same length and angles measuring the same degrees are called regular polygons. There are also such things as irregular polygons. When a shape has different sized lines and different types of angles, it is called an irregular polygon.
