Question

Quadrilateral ABCD has coordinates A(3,5) B(5,2) C(8,4) D(6,7). quadrilateral ABCD is a?

Answer 1

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.
