2 Question content area top Part 1 Rectangles have four right angles and opposite sides that are parallel. a. Is the figure shown a rectangle? Explain. b. If not, how could the points change so it would be a rectangle? -4 -2 2 4 6 8 -6 -4 -2 2 4 6 x y AD C B x y graph Question content area bottom Part 1 a. The slope of AB is enter your response here and the slope of CD is enter your response here, so AB and CD ▼ are not are parallel. The slope of BC is enter your response here and the slope of DA is enter your response here, so BC and DA ▼ are are not parallel. These slopes also show that ▼ at least one pair of adjacent sides is not each pair of adjacent sides is perpendicular, and so ▼ each of the angles is at least one of the angles is not a right angle. The figure shown ▼ is is not a rectangle.
