Four parallel lines are drawn in a rectangular sign. the sign is painted using two colors in an alternating pattern, as shown. which statements must be true about the two congruent, shaded figures? check all that apply. a.) the figures are rectangles because they are formed inside a rectangle. b.) the figures are rhombi because they are formed by four congruent line segments. c.) the figures are trapezoids because each has exactly one pair of parallel sides. d.) the figures are parallelograms because their opposite sides are parallel. e.) the figures are quadrilaterals because each has four sides. the answer is not a, d, & e, for some reason.
