Exam points

  • use perpendicular height rather than a sloping side in each area formula
  • derive a shared height from a parallelogram before calculating an adjacent trapezium
  • rearrange the trapezium formula to find a missing parallel side or height

4.9.D The area of parallelograms and trapezia question 1

ABCD is a trapezium with one line of symmetry.
