Hello, Ants!

I have a game plan . . .

We have four unknowns; we will need four equations.Code:(2,5,17) ♥ C * * D * * (x_{d},y_{d},13) ♥ * * * * * * ♥ (x_{b},y_{b},13) * * B * * A ♥ (13,30,9)

The sides of the square are equal.

. .

These give us three equations.

The diagonals are equal.

. .

. .

This gives us the fourth equation.

Can you take it from here?
