Answer:
Explanation:
(a) A slice through the center, parallel to a side:
To visualize this slice, imagine cutting the rectangle horizontally, exactly in the middle, so that you end up with two smaller rectangles stacked on top of each other. The resulting cross section will be a rectangle with the same width as the original rectangle, but only half of its length.
(b) A slice that cuts through the left top edge and the right bottom edge:
To visualize this slice, imagine cutting the rectangle diagonally from the top left corner to the bottom right corner. The resulting cross section will be a right triangle, with one of its legs being half of the original rectangle's width, and the other leg being half of its length.
(c) A slice that cuts across a corner through three sides of the rectangle:
To visualize this slice, imagine cutting the rectangle diagonally from one of the top corners to the opposite bottom corner, and then continuing the cut along one of the sides of the rectangle, until you reach the middle of that side. The resulting cross section will be a trapezoid, with one of its parallel sides being half of the original rectangle's width, and the other parallel side being half of its length. The two non-parallel sides will be angled.
