Types of Geometric Shapes

Video Transcript

"So what are some types of geometric shapes? Hi, I'm Jimmy Chang. I've been teaching college mathematics for nine years, and throughout your lifetime, you will see a lot of different shapes pertaining to geometry, and you'll be asked to find the various areas, perimeters, or even volumes of those geometric shapes. But here's just a few to help get you started -- an introduction, if you will. Now, we all recognize this kind of a shape -- that of a circle. The one...the only one that's really round and round and round. But then when we get to the three-sided triangles -- and three-sided closed shape is known as a triangle. Now, if it's four sides, you have a couple of options here. You have a rectangle, a square, in which all the sides are equal, or you can have, for example, a trapezoid, where if you notice, the top side is smaller -- shorter, if you will -- than the bottom side. Now, the more sides that you have, you're going to have more sophisticated shapes like that of a hexagon, which is six-sided. Now, everything but the circle -- if you haven't already learned it -- has one word, and that is that of a polygon. And a polygon is simply a closed shape with three or more sides, but the emphasis is on closed. But I'm Jimmy Chang, and that's an introduction on the various types of geometric shapes."
