From the given graph, the image is a trapezoid. Therefore, The first option, "t<span>he polygon is a rectangle" is incorrect. The second option "</span><span>Adjacent sides of the polygon are perpendicular." cannot be true as well because trapezoid has one the adjacent sides which is not perpendicular. Third option" </span><span>Opposite sides of the polygon are parallel", this can't be true as well because only two sides are parallel. Fourth option " </span><span>The slope of side c is 0.", this is true because line c is a horizontal line with zero rise and maximum run. Therefore, Slope = 0 </span>÷ 9 <span> = 0
