Answer:

$144 {v}^{2} + 76 = 85 \\ 144 {v}^{2} = 85 - 76 \\ 144 {v}^{2} = 9 \\ {v}^{2} = 9 \div 144 \\ \\ {v}^{2} = \frac{9}{144} \\ \\ {v}^{2} = \frac{1}{16} \\ \\ v = \sqrt{ \frac{1}{16} } \\ \\ v = \frac{1}{4} \: , - \frac{1}{4} \\ \\ v = 0.25 \: , - 0.25$

Use the distance formula. The distance formula is:

$\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}$

If you input the values, you will get:

A to B= $\sqrt{13}$

B to C= $\sqrt{13}$

C to D= $\sqrt{13}$

D to A= $\sqrt{13}$

It is a square.

Hope that helped!
