Determie the most precise name for each of the quadrilaterals below. justify your answer with math and an explanation b(-4, -5), e(1, -5), f(02, -1), g(-7, -1)

It is a trapezium.

Step-by-step explanation:

The length of BE = (1 - - 4) = 5.

EF = sqrt((-1 - - 5)^2 + (2 - 1)^2 = sqrt 37

FG = (2 - -7) =  9

GB = sqrt (-1 - - 5)^2 + (-7 --4)^2 = sqrt 25 = 5.

Slope of BE = (-5 - -5) = 0  

Slope of EF =  (-1--5) / (2-1) = 4

Slope of FG =  (-1 - -1) = 0

Slope of GB =  (-1- -5)/ (-7- -4) = -4/3

So the quadrilateral has one pair of opposite parallel sides, whereas the other 2   are not parallel. so it is a trapezium.
