Diagonals of a parallelogram ____ each other.

Class 9QuadrilateralsGeometry — Quadrilaterals
  • ABisect
  • BAre equal to
  • CAre perpendicular to
  • DTrisect

Step-by-Step Solution

In every parallelogram the diagonals bisect each other (each diagonal cuts the other into two equal halves). They are equal or perpendicular only in special cases.
Answer: A) Bisect

Key idea: Special parallelograms

**Rectangle** (parallelogram + all angles 90°):
- All properties of a parallelogram.
- Diagonals are EQUAL (in addition to bisecting each other).

**Rhombus** (parallelogram + all sides equal):
- All properties of a parallelogram.
- Diagonals bisect each other AT RIGHT ANGLES.
- Diagonals also bisect the angles of the rhombus.

**Square** (rectangle + rhombus):
- All properties of both.
- Diagonals: equal, bisect at right angles, AND bisect angles.
