A parallelogram inscribed in a circle is a:

Think it through first, then pick an option.

  1. a rhombus
  2. b rectangle
  3. c square
  4. d trapezium
Answer and explanation

Correct answer: b rectangle

Opposite angles are equal and supplementary, so each is 90°: a rectangle.

Why the other options are wrong

  • a rhombus: A rhombus has equal opposite angles, but supplementary ones force 90° each; a general rhombus cannot be inscribed.
  • c square: A square is a special rectangle; not every inscribed parallelogram is a square, but all are rectangles.
  • d trapezium: A trapezium has only one pair of parallel sides; a parallelogram has two.
