Need help please and thank you ​

Answer 1

Answer: B. No, the adjacent sides are not perpendicular.

Explanation:

B(2,4), A(4, -1), C(-2, 2), D(0, -3)

Slope of BA =
`(4-(-1))/(2-4) = (5)/(-2)`

Slope of CD =
`(2-(-3))/(-2-0) =(5)/(-2)`

BA║CD

Slope of BC =
`(4-2)/(2-(-2)) =(2)/(4) =(1)/(2)`

Slope of AD =
`(-1-(-3))/(4-0) =(2)/(4) =(1)/(2)`

BC║AD

Slope of BA
`=(5)/(-2)`

Slope of BC
`=(1)/(2)`

BA is not perpendicular to BC
