We always don't have the luxury of colors, this one is clearly the And if we were to connect D and C, this would also be another
Talk in mathematical terms, a line means something slightly different. You might call it a line, but we'll call it a line segment, 'cause we'll see when we
So what would we call this thing, all of the points that connectĪ and B along a straight, and I'll use everyday language here, along kind of a straight line like this? Well, we'll call this a line segment. Points, including that point that connect that point and another point? So all of these points right over here. One point to another? So what if we started at one point and we wanted all of the What if we wanna moveĪround a little bit more? What if we wanna get from You really can't move around on a point, all they do is specify a position. You know that you would have to circle that point right over there. So if someone says, "Hey, circle point C," you know which one to circle.
This would be point C, and this right over here could be point D. So, for example, this could be point A, this could be point B, Refer to the green point or the blue point or the pink point, and so in geometry, to refer to points, we tend to give them labels, and the labels tend to have letters. Refer to the different points, and not everyone has the luxury of a nice, colored pen like I do, otherwise they could Maybe I have another point over here and then I have another point over here and then another point over there. Now, there are differences between points, for example, that's one point there. You would no longer be at that point, so youĬannot move on a point. 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
