Question

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

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

Answer 1

Please explain as well. I want to know how to do this myself..

Answer 2

ok so the x axis and y axis lie in the middle of the square
(pretend that the lines are perfectly in the middle

then the corner up in the top right of the sqare is (a,b).

So the corner to the left of it is on the positive side of y so its (_,+b) right?
but for that comer its on the negative side of x yeah? so its -a and so for that corner the coordinates are (-a,b).

See if you can do the rest if you can get this.
