Definitely a square
I believe a parallelogram would also have this property
* * * * *
A rhombus: Yes. All other parallelograms: No.
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
Parallelograms.
squares
In a quadrilateral, the diagonals do not have to bisect each other or be perpendicular. These properties hold true for specific types of quadrilaterals, such as rectangles (where diagonals bisect each other and are equal) and rhombuses (where diagonals bisect each other at right angles). However, in general quadrilaterals, the diagonals can have various lengths and angles without conforming to these conditions.
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.
Rhombus, Square, Rectangle AND Parallelogram (APEX) o. O
They are 4 sided quadrilaterals such as a square, a rectangle, a rhombus, a parallelogram and a kite.
