# Reflection on Polygons

by on March 4, 2011

We did a series of tuning in projects on polygons for our upcoming unit of geometry, and I learned a few things. First I learned that polygons have to pass certain requirements to be known as a polygon, through a BrainPop video. A polygon has to have 3 or more sides, and has to be a closed figure. Also, it has to consist of straight lines. There are two types of polygons, regular and irregular. A regular polygon has sides and vertices of the same length and angles respectively. An irregular polygon’s sides and vertices can be of different length and angles. In, class, we discussed and made a connection about polygons. We asked ourselves, what does -gon mean? We made the interpretation that -gon means sides, because of the examples we saw on that BrainPop video. ( trigon means a polygon with 3 sides, pentagon is a polygon with 5 sides, etc) Another small activity we did was watch a video about polygons. It’s for younger children, but hilarious all the same.  I think measuring the area of these polygons will be hard, but I’ll try to learn ‘em.

Measuring area of polygon is as easy as taking breakfast. You can do it.
