No
It can be a square or a rhombus
The diagonals of a kite cross each other at right angles
Yes, and at right angles.
A square, a rhombus and a kite have diagonals that intersect each other at right angles.
The diagonals of a square cross each other at right angles is one example
Yes and they are perpendicular to each other thus forming right angles of 90 degrees
No
It can be a square or a rhombus
The diagonals of a kite cross each other at right angles
The diagonals of a square (which always bisect each other) are the same length.
They are either kites or (if the diagonals bisect each other) rhombuses.
No but the diagonals of a square bisect each other at right angles
Not for every parallelogram. Only for a rhombus (diamond) or square will the diagonals bisect the opposite angles they connect, and diagonals are perpendicular. In rectangles, the diagonals do not bisect the angles and are notperpendicular, but they do bisect each other.
Square
Yes, and at right angles.
A square, a rhombus and a kite have diagonals that intersect each other at right angles.
