Question

Could you help me with coordinates?
The coordinate axes contain two sides of a square ABCD. If A(0, a) and B(0, 0) are two vertices of the square:

State the coordinates of the other two vertices so that all coordinates are > 0

C ( _ , _ )
D ( _ , _ )

State the coordinates of the other two vertices so that some coordinates are < 0

C ( _ , _ )
D ( _ , _ )

Answer 1

Have you tried to draw the square?

Answer 2

I will draw the first square and then you try the second one. I think you will see the points once you see the square drawn.
