A diagonal joining opposite angles is the principal diagonal. It may or may not bisect the angles, and that does not affect its name.
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.
a rhombus
A square has 2 diagonals that are equal in length and bisect each other at right angles.
Yes, in the figure of a kite one diagonal bisects the other. They do not bisect each other.
A diagonal joining opposite angles is the principal diagonal. It may or may not bisect the angles, and that does not affect its name.
Yes. In a rhombus (and in a square), the opposite angles that each diagonal connects are bisected by the diagonal.
Each diagonal of a rhombus would never bisect a pair of opposite angles, but the diagonals are perpendicular to each other
Opposite angles do not bisect any shapes.
No. In general it does not. Only if the rectangle is, in fact, a square.
Yes and at right angles
No, a rectangle's diagonals do not bisect opposite angles.
In rhombuses and squares the diagonals bisect opposite angles.
The diagonals will not always bisect opposite angles in the rectangle.
The diagonals will not always bisect opposite angles in the rectangle.
Yes.
The diagonals of a rectangular shape will only bisect opposite angles if, in fact, the shape is a square. Otherwise they will not bisect them.
