Question 4 (Multiple Choice Worth 2 points)

Which of the following shapes is not one of the parts of this composite figure?

the figure has three connected quadrilaterals which are stacked, one on top of the other. These quadrilaterals are the same size. The length of each is greater than the width. The top and the bottom quadrilaterals have straight and parallel sides that form right angles. The sides of the quadrilateral in the middle are slanted and do not form right angles. A slanted line extends from the top right vertex of this middle quadrilateral to the inside, bottom. Another slanted line extends from the bottom left vertex up to the inside top. These lines form a quadrilateral with slanted sides and a 3-sided figure on either side of it.
