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.
