Hi, my name is Marija, I'm a mathematician and today, we're going to talk about quadrilaterals in real life. So, a quadrilateral is a four sided, and closed figure. And you are going to see a lot of them around you everyday. So, one quadrilateral that you might find familiar, if you are in a park, is you might see a kite, right. So, a kite is one form of quadrilateral, because it does have the four sides and it is in a closed figure. Another quadrilateral that you're going to see a lot more of, is a rectangle. Because things like your bedroom walls are rectangular, things like your desk in your classroom is probably rectangular. Your blackboard is probably rectangular. So, all of those things are rectangles. And then, of course, squares are rectangles as well, except they have sides that are all the same size. So, you might see a lot of those around your life as well. So, if your walls are all the same size, now instead of just being a rectangular, rectangle, they're also classified as a square. And then, when we talk about more three-D stuff, we see a lot of rectangular prisms also, in real life. Like your textbooks, like your bedroom mattress, things like that. And the same thing applies to a square, right. Ice cubes are actually squares that are three-D, so they're called cubes. So, you do see quadrilaterals everywhere in real life. My name is Marija and I just showed you some everyday quadrilaterals.
