Prove that this quadrilateral is a rectangle. explain how you would do this (you don't actually have to find the values).

If we take a look at the properties of a rectangle, we know that the opposite sides must be equal.

(A=0,3)
(B=3,0)

(C= 1,-2)
(D=-2,1)

they are both equally apart.

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.
