Four parallel lines are drawn in a rectangular sign. The sign is painted using two colors in an alternating pattern, as shown.

A rectangle is shown. 4 parallel lines are drawn diagonally from one side of the rectangle to the opposite side. The shapes formed by the parallel lines are colored in an alternating pattern.

Which statements must be true about the two congruent, shaded figures? Select two options.

The figures are rectangles because they are formed inside a rectangle.
The figures are rhombi because they are formed by four congruent line segments.
The figures are trapezoids because each has exactly one pair of parallel sides.
The figures are parallelograms because their opposite sides are parallel.
The figures are quadrilaterals because each has four sides.

This statement is true. Given that the shapes are formed by lines drawn parallel to each other and within a rectangle, the opposite sides of each shape will indeed be parallel.

The figures are quadrilaterals because each has four sides.

This statement is true. By definition, any shape with four sides is a quadrilateral. The figures are formed by intersecting lines, resulting in four-sided shapes.
