    Naming coordinates

    Hey guys, I'm totally confused with this problem Imageshack - 49809274.jpg

    I know that w= (a,a) and z = (a,0)
    But I want to know how do you get that? I don't understand this at all.
    Can someone walk me through at how to work these kind of problems?

    Oh, sorry it is a square.

    You can know that only if the figure is known to be a square.
    You did not give us that bit of information.
    Squares have sides of equal length.

    It's a square and each side is a units long. So you have your points at (0,0), (a,0), (a,a), and (0,a)

    point (0,a) on the graph indicate that y = a
    so in the square all side the same it mean that all side = a
    from there you get for point w at (a,a) ; x = a and y = a
    and point z at (a,0) ; x = a and y = 0
