![]() Interesting quadrilateral, because a square falls in Say make a square corner, that's where it comes from. And a square has, the corners are square. But what about our square? Is a square a rectangle? Well let's draw it out. This is a parallelogram,īut not a rectangle. That you have, the squareĭoes not fit over here. That does not, a squareĭoesn't fit in the corners the way that it fits right over here. So for example, this right over here would not be a rectangle. You could put a little square there, if you wanna think about it that way. That's called a rightĪngle right over there. ![]() So in a rectangle, the things come in to, I guess you could call We use the word rectangle? Well one way to think about it is they way that they come But what makes it a rectangle? It's definitely a parallelogram, but what makes it, why do Never going to intersect if you kept going on and on and on, or they're never going And this side and this side are parallel. Why is it? Well it's definitely a parallelogram. ![]() To be a parallelogram, but that by itself does Word rectangle in the past, but let's think a little bit more about what makes a rectangle. Rhombuses, or rhombi, is they're squares, and you could kind of view them as kind of a pushed over version of squares, if a square was moving really, really, really fast in a cartoon, that's what my brain thinks That the opposite sides of a square are parallel. Is a square a rhombus? Are all the sides the same length, and are the opposite sides parallel? Well we already said Maybe a square is a rhombus," and I want you to think about that. So opposite sides are parallel and all the sides are the same length. So it's a parallelogram,īut it's not a rhombus because the blue sides are ![]() And these two opposite sides are parallel. It's a parallelogram because that side, these opposite sides are parallel. So for example, this that I'm drawing, that is a parallelogram,īut it is not a rhombus. The opposite sides need to be parallel, and all the sides have to be equal. The opposite sides need to be parallel, but that's not, by itself, So the rhombus is a type of parallelogram. Types of four sided shapes, or quadrilaterals. So now let's talk about, let's talk about more That is not a parallelogram would be this one right over here, because none of the So this one right over here is not a parallelogram. Things that are not parallel is if the lines kept going, they would cross each other at some point, while these lines, these lines right over here, they're never going to cross each other. This is parallel to this." But then you would see that You might say, "Wait, "I see two opposite sides are parallel." You might say, "Look, So what's not a parallelogram? Well, something like, something like this would not be a parallelogram. It's a special type of parallelogram because this side is going in the sameĭirection as that side, and this side, and this side, whoops, let me do that in yellow, and this side is parallel to that side. So what are otherĮxamples of parallelogram? Well even your classic square, even your classic square, is a parallelogram. And these two sides, these two sides right ![]() So those two sides are pointed, are parallel, is the word we say. They're going, they're going, if I were to draw an arrow, if I were to draw an arrow here, those arrows are pointed in the same way. Opposite to this side, and they're pointed in the same direction. So what do I mean by that? So something like this, something like this, would be a parallelogram. And parallel is just another way of saying that they're going in the same direction. So a parallelogram is a quadrilateral, and as we learn more math, we'll learn other ways So now let's think about the different types of quadrilaterals, or the different categories Sides, a hundred sides, none of that is going You could say, no sides, it's just one big curve, it's a circle. It has one, two, three, four, five sides. A pentagon that has five sides, that would not be a quadrilateral. So what's not a quadrilateral? Well, a triangle would even this is a, let me make it look even weirder, even this is a quadrilateral. So that is a quadrilateral, this is a quadrilateral, this is a quadrilateral. Quad as part of a word, it's a good, it's a good sign that you're dealing with Talk about in this video is shapes with four sides, and the mathy word for ![]()
