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=
`√(13)`

B to C=
`√(13)`

C to D=
`√(13)`

D to A=
`√(13)`

It is a square.

Hope that helped!
