# Drawing a quadrilateral on the coordinate plane example

We're making a four-sided shape called a quadrilateral using line segments! We use four points on a graph: (0,9), (0,-7), (8,-7), and (8,0). We connect these points to form our quadrilateral. Isn't shape-making fun? Created by Sal Khan.

- How do you draw a quadrilateral on the coordinate plane?(8 votes)
- You draw the quadrilateral on the coordinate plane by plotting the points given. If it says "3 units to the left of (3, 4) it is (0, 4). Simply use the coordinate plane and grid to help you. Hope that I helped!(15 votes)

- at0:22I thought I was going blind.

Am I the only one who thought that?(12 votes) - Umm...well this video doesn't really help understand "Drawing polygons with coordinates"....I'm still pretty confused.....(10 votes)
- One vertice is one of the points of a shape, whether that be a square, rhombus, etc. So if you place a vertice of one of the lines at one point and the other vertice of the line at another point (on a quadrilateral), you have formed one of four lines. And you overlap these until you make your shape!(2 votes)

- does anyone acutlly like doing math(6 votes)
- One of the exercicies asked me to do an hexagon. But I can only make 3 dots. Help !(8 votes)
- Meaning? I might be able to help. Does it ask for three dots or another way. You might be understaning it wrond. Check again and them tell us what is says. Or press Ctrl and PrtSc and paste the image here. You can also send the link here. Or never mind about the link.(1 vote)

- How do you know which goes where?(7 votes)
- What does he mean when he sage savage vertex(6 votes)
- I know how to spot the answer but i'am confused how to make the shapes in your videos you should add more details like the video was only 1 minute can you do that and make another better video please?(6 votes)
- I'm still having a little bit of trouble with this.(4 votes)
- Ok, so this can be a tough one, but it's rather simple! What you are doing is finding the points and connecting them to other points to create a shape.(4 votes)

- Don't polygons have 4 sides?(3 votes)
- No, any shape without curved or not closed sides are polygons. It's not just limited to shapes with 4 sides.(6 votes)

## Video transcript

- [Instructor] Use the line segments below to create a quadrilateral, so a four-sided figure, with vertices at the following points. So they give us four
coordinates right over here. So those have to be where the sides of our
quadrilateral intersect. So one is at the point 0,9. So our x-coordinate is 0, so we're at 0, and then our y-coordinate or
our vertical coordinate is 9. So we have to have, we need to have a vertex right over here. Now the next one is at 0,-7. So 0,-7. So lemme just put something here. We can later rearrange it to
see what actually makes sense. Then we have 8,-7. So 8,-7. 8,-7 is right over here. It feels like this
might be the right edge. So I'll put its other point right at 8,-7. And then finally, 8,0. 8,0. Well, 8,0 is right over here. So it looks like I have a point on every
one of the vertices. So now I just have to connect to these two and I'll have a four-sided figure. So let me take this there, bring this one over, and then let me move this one up, and then bring this one down, and there you have it. I think I've got my quadrilateral.
