If you were on this point and you moved in any direction at all, Now, what's interesting about a point is that it is just a position that you can't move on a point. It's what we would call it in just everyday language as well. We could have called this an armadillo, but we decided to call this a point, which I think makes sense because And the fun thing about mathematics is that you can make definitions. That dot right over there is just a point, it's just that little point on Now, with that out of the way, let's just start from the basics, a basic starting point from geometry, and then we can just grow from there. Visually mathematical things that we understand can in some way be categorized in geometry. So it's almost everything that we see, all of the Things like patterns and three-dimensional shapes,

Things more and more precisely as we go further and further on, but it also encapsulate Learning about geometry, you learn about linesĪnd triangles and circles and you learn about angles and we'll define all of these

Geometry really is the studyĪnd trying to understand how shapes and space and things that we see So when someone's talking about geometry, the word itself comesįrom earth measurement and that's kind of not so bad of a name, because it is such a general subject. And metry, or the metric system, and this comes from measurement. Like a C right over there, this refers to the earth. Have the root word geo, the same word that you see in things like geography and geology, and this refers to the earth. What geometry means, 'cause you might recognize And I guess the best place to start is to even think about Or some of the characters that we use when we talk about geometry. Do in this video is give an introduction to the language
