Question

Can you please help me with this coordinate problem? I want to know how to do these myself, so could you explain?

The x-axis and y-axis are lines of symmetry for a square. If one of its vertices has coordinates (a, b), find the other three vertices?
The answers should look like this:

(a,_), (_,-b), (_,_)

Answer 1

So what do you know about a square? That is the place to start.
All the sides are going to be equal.
That means if the axis of symmetry are the x and y axis, they will cut each side of the square in half.
Correct?

Answer 2

Okay, that's true..
