Which of the following quadrileterals is a reguler quadrilateral?
Which of the quadrilaterals has all angles as right angles, opposite sides equal and diagonals bisect-each other?
Which of the parallelograms has all sides equal and diagonals bisect each other at right angle?
In a parallelogram, opposite sides are equal, opposite angles are equal and diagonals bisect each other. In a rhombus diagonals intersect at right angles. In a rectangle diagonals are equal. A quadrilateral can be constructed uniquely if the lengths of its four sides and a diagonal are given.
In an isosceles parallelogram, we have:
