Thread: 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
