Use the distance formula. The distance formula is:

[latex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/latex]

If you input the values, you will get:

A to B=[latex]\sqrt{13}[/latex]

B to C=[latex]\sqrt{13}[/latex]

C to D=[latex]\sqrt{13}[/latex]

D to A=[latex]\sqrt{13}[/latex]

It is a square.

Hope that helped!
