Question

How do I find the coordinate of a point if three of the vertices are given?

Answer 1

What do you mean? What point in particular are you looking for?

Answer 2

Three of the four vertices of the parallelogram are given and I need to find the fourth

Answer 3

can you attach the picture for us so we can help you better?

Answer 4

I can't Becaus I'm on my iPad but the three vertices of parallelogram jklm are j(-5,2) k(2,2) l(4,-2) and I'm trying to find m

Answer 5

wait i am working on a coordinate grid right now.

Answer 6

Ok thanks

Answer 7

just a few moments :)

Answer 8

Alright no problem

Answer 9

do you have any mulitple choices?

Answer 10

No this is just on a worksheet

Answer 11

i am guessing to place it on (-3,-2)

Answer 12

Ok and how exactly did you come up with that?

Answer 13

i cant bring the image in here. that's the problem. but what i did is aligned the vertex on the same line of -2 as l. then tried to figure out which would best be the parallelogram.

Answer 14

Hi! Sorry, I didn't notice the reply! For any general parallelogram,
opposite sides have the same length and slope!

Answer 15

Ok thank you calculusxy

Answer 16

Given those 3 points, you can see how you got from the top left to the top right. Then you can reverse that to go from the bottom right to the bottom left.

Answer 17

Actually, instead, it would be easier to see what you do to get from the top right to the top left. Then you can use the same \(x\) and \(y\) change to get from the bottom right to the bottom left.




Another way to go is look at another side to get to your mystery point!

Answer 18

I hope this helped! I have to go. Take care!
