Sorry, another question.
** Determine whether parallelogram ABCD is a rhombus, a rectangle, or a square. List all that apply. Explain your reasoning.
1) A(12,0), B(6,-6), C(0,0), D(6,6)
I know to do this. I just don't know if it's a rhombus, rectangle, or a square. For AB I got -6/-5; BC= 6/-6; CD= 6/6; and AD= 6/5..........is this all right? And how can I tell if it's either one of these (any easy way to tell)?
