Answer» Except (c) all are correct Explanation:A rectangle is considered a special case of a parallelogram because: A parallelogram is a quadrilateral with 2 pairs of opposite, equal and parallel sides. A rectangle is a quadrilateral with 2 pairs of opposite, equal and parallel sides BUT ALSO forms right angles between adjacent sides.A rhombus is a parallelogram with four congruent sides.A trapezium is NOT a parallelogram because a parallelogram has 2 pairs of parallel sides. But a trapezium only has 1 pair of parallel sides.A kite is a quadrilateral with two adjacent pairs of sides of equal length. A rhombus is a quadrilateral with all sides of equal length. So a rhombus does have two pairs of adjacent sides of equal length and is, therefore, a kite. |
