Given the length of one diagonal, which of the following can be drawn?

Think it through first, then pick an option.

  1. a Rhombus
  2. b Square
  3. c Rectangle
  4. d Parallelogram
Answer and explanation

Correct answer: b Square

A square's diagonals are equal and bisect at right angles; one diagonal fixes it.

Why the other options are wrong

  • a Rhombus: A rhombus has two different diagonals; knowing one does not give the other.
  • c Rectangle: A rectangle's diagonals are equal but its sides differ; one diagonal does not fix them.
  • d Parallelogram: A parallelogram needs both diagonals and the angle between them.
