(-3,-9) , (2,4) , (2,-9) , (-3, 4)

(5,-6) , (5,0) , ( 1,0) , ( 1, -6)

Answer 1

Can you re-write those using numbers and actual commas and such? Would make it a lot easier to answer the Q...

Answer 2

Rewrote :)

Answer 3

Okay ^^ so to figure this out, you need to look at the differences between x and y-values and see if they are equal--essentially you're finding the length of the sides in doing this--and if they are the same, it's a square.
so the change in x values should = the change in y values, assuming the square is not turned on the plane.
