Reuse & Permissions WebThe word “pentagon” comes from the Greek word “pentagonos”, which means “five-angled”. A regular pentagon has five internal angles that form corners. The angles in all the corners or regular and irregular pentagons will always add up to 540º. Take a look at the video below for some examples of polygons, including pentagons.
