All angles are 90º. Diagonals bisect each other at right angles. A quadrilateral whose diagonals bisect each other is a parallelogram, as we will show in this exercise. 3. Square. All four sides are equal Diagonals bisect each other Diagonals bisect opposite angles One angle between the diagonals is `60^0`" The diagonals bisect each other. Opposite sides are parallel and equal. In parallelograms (types of quadrilaterals), the diagonals bisect each other. Quadrilaterals do not bisect each other.

One of the properties of a parallelogram is that its diagonals bisect each other. (i) bisect each other (ii) are perpendicular bisectors of each other (iii) are equal - 1445472

This is a converse theorem – that shows that if the diagonals bisect each other, the quadrilateral must be a parallelogram. Rectangle. "Which of the following quadrilateral is not a rhombus? Parallelogram 2. "Question 4 Name the quadrilaterals whose diagonals. Opposite sides are parallel and all sides are equal. They could in special cases.

There are six basic types of quadrilaterals: 1. All angles are 90º. Types of Quadrilaterals and their Properties. Theorem 8.7 If the diagonals of a quadrilateral bisect each other, then it is a parallelogram.
