Kite: A quadrilateral in which two disjoint pairs of consecutive sides are congruent (“disjoint pairs” … A parallelogram and rhombus can only be rectangles when their interior angles are each 90°. A rhombus is not always a square as it is not required to have congruent angles, the angles can be different. 2. A parallelogram is a shape with four sides and two pairs of parallel sides. Since rhombuses are quadrilaterals with 4 congruent sides, squares are by definition also rhombuses. The diagonals bisect each other 3. Why is a trapezoid a quadrilateral, but a quadrilateral is not always a trapezoid? 1 0. Because we are dealing with a parallelogram, you know that opposite sides are congruent.

Parallelograms are defined as a shape with opposite, but parallel sides. DEFINITION of PARALLELOGRAM: There is one right angle in a parallelogram and it is not a rectangle. The rectangle is a special case of a parallelogram in which measures of its every interior angle is 90 degree. so, a rhombus is sometimes a rectangle, since a square is always a rectangle. A rectangle has all 90º angles, so we're good in the regard. An equiangular rhombus is a square. A rectangle is ALWAYS a parallelogram, because its opposite sides are parallel. The main difference is that a rectangle always has angles of 90°, while that of a parallelogram may vary. Please enable Cookies and reload the page. Search.
