Answer:
B. ABCD is a trapezoid because it has at least
one pair of parallel sides.
Explanation:
the two points A(-3,-1) and D(5,-1) have the same y-coordinates
Then
The line AD is parallel to the x-axis
On the other hand,
the two points B(1,5) and C(5,5) have the same y-coordinates
Then
The line BC is parallel to the x-axis.
We obtain :
• AD is parallel to the x-axis
• BC is parallel to the x-axis.
Therefore
AD // BC
Conclusion:
ABCD is a trapezoid because it has at least
one pair of parallel sides.
