Quadrilaterals do not bisect each other. They could in special cases. In parallelograms (types of quadrilaterals), the diagonals bisect each other.
A square has two diagonals that bisect each other at 90 degrees
Square, rhombus and a kite have diagonals that bisect each other at 90 degrees
squares
Parallelograms.
Arrow head
A parallelogram a rectangle a square and a rhombus
They are either kites or (if the diagonals bisect each other) rhombuses.
Not necessarily.
They are 4 sided quadrilaterals such as a square, a rectangle, a rhombus, a parallelogram and a kite.
Rhombus, Square, Rectangle AND Parallelogram (APEX) o. O
A quadrilateral whose diagonals bisect each other at right angles is a rhombus. each other at right angles at M. So AB = AD and by the first test above ABCD is a rhombus. 'If the diagonals of a parallelogram are perpendicular, then it is a rhombus
