Identify trapeziums

Key Notes :

🏫A trapezium is a quadrilateral with one pair of parallel sides. A quadrilateral is a four-sided polygon.

🏫 In diagrams, we mark parallel sides with matching arrows.

Learn with an example

✈️ Is this polygon a trapezium?

  • yes
  • no
  • To see if a polygon is a trapezium, first check that it is a quadrilateral. Then check that it has one pair of parallel sides.
  • This polygon has four sides. It is a quadrilateral.
  • This quadrilateral also has a pair of parallel sides. Parallel sides are usually marked with matching arrows.
  • So, it is a trapezium.
