Question

If given only the coordinates of the vertices, describe a process you could use to find the perimeter and area of a square.

Answer 1

Do you know what is a vertex, and how to graph it?

Answer 2

So lets make the general form of a square if the vertices are given...

Answer 3

Well, in this case ax is equal to cx but let's suppose they would be different. Like on the board. So, as you can see if we do have the vertices we can find the length off the square and if we know the length of a square, we can easily find the perimeter (the sum of all sides) and the area (the side square).
Is that clear : ")
