Square
The diagonals of a parallelogram are congruent (equal in length) and bisect each other.
No but they bisect each other at right angles
No. It is false. If both of those conditions are met, then the quadrilateral is a square.
In general they are not; they are perpendicular only if the rectangle is also a sqare. However, the diagonals of a retangle have another attribute: They are of equal length and bisect each other.
The diagonals of a square bisect each other at 90 degrees
The diagonals of a square (which always bisect each other) are the same length.
Square, rhombus and a kite have diagonals that bisect each other at 90 degrees
No but the diagonals of a square bisect each other at right angles
Yes
The diagonals of any rhombus bisect each other. A square is a special kind of a rhombus.
A square has two diagonals that bisect each other at 90 degrees
Square
Yes they do, in a square.
Square, Rhombus
A square and a rhombus
Only for a square or rhombus (diamond shape). The diagonals of a rectangle bisect each other, but are not perpendicular and do not bisect the opposite angles they join.
