Which of the following is called 'Trapezium'?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Two opposite sides are parallel and two opposite sides are non-parallel
A trapezium is a quadrilateral with one pair of opposite sides parallel; the other pair of opposite sides is not parallel. The parallel sides are its bases.
Why the other options are incorrect
Option (1) All the sides are equal — Incorrect. This describes a rhombus (or a square).
Option (2) Two opposite parallel sides are equal — Incorrect. Opposite sides both equal and parallel make a parallelogram; a trapezium’s parallel sides are unequal.
Option (4) A pair of adjacent sides are equal — Incorrect. Two pairs of equal adjacent sides make a kite.
