Answer:

Proved

Explanation:

Given


B =(-2,-1)


U = (0,3)


G = (3,2)


S = (4,-3)

Required

Prove BUGS is a trapezoid

Given the coordinates, to prove a trapezoid; all we need to do is to check if one pair of sides is parallel.

Taking BU and GS as a pair

First, we calculate the slope using:


m = (y_2 - y_1)/(x_2 - x_1)

For BU


B =(-2,-1) ---
(x_1,y_1)


U = (0,3) ---
(x_2,y_2)

So, we have:


m = (3 - -1)/(0- -2)


m = (4)/(2)


m = 2

For GS


G = (3,2) ---
(x_1,y_1)


S = (4,-3) ---
(x_2,y_2)

So, we have:


m = (-3-2)/(4-3)


m = (-5)/(1)


m = -5

The slope of BU and GS are not the same; hence, they are not parallel.

Taking BS and GU as a pair

Calculate the slope

For BS


B =(-2,-1) ---
(x_1,y_1)


S = (4,-3) ---
(x_2,y_2)

So, we have:


m = (-3 - -1)/(4- -2)


m = (-2)/(6)


m = -(1)/(3)

For GU


G = (3,2) ---
(x_1,y_1)


U = (0,3) ---
(x_2,y_2)

So, we have:


m = (3-2)/(0-3)


m = (1)/(-3)


m = -(1)/(3)

The slope of BS and GU are the same; hence, they are parallel.

BUGS is a trapezoid because BS and GU have the same slope
