- 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!(9 votes)
- at0:22I thought I was going blind.
Am I the only one who thought that?(9 votes)
- Umm...well this video doesn't really help understand "Drawing polygons with coordinates"....I'm still pretty confused.....(8 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)
- 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)

- 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)
- What are the order of the quadrants again.(4 votes)
- Here is the quadrant orders:
I = Top Right
II = Top Left
III = Bottom Left
IV = Bottom Right
The quadrants are separated by the x and y axis. If one is in the middle of an axis point, you can consider that to be in between two numbers. Hope this helps! -Johnny Unidas(3 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?(5 votes)
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 need to have a vertex right over here. Now, the next one is at 0, negative 7. So let me just put something here. We can later rearrange it to see what actually makes sense. Then we have 8, negative 7. So 8, negative 7 Is right over here. It feels like this might be the right edge. So I'll put its other point right at 8, negative 7. And then finally, 8 comma 0. Well, 8 comma 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 let me move this one up, and then bring this one down. And there you have it. I think I've got my quadrilateral.
