Worksheet

  1. a triangle with no equal sides → scalene triangle
  2. 4 right angles, with only opposite sides equal → rectangle
  3. 4 equal sides, but no right angles → rhombus
  4. exactly 1 pair of parallel sides → trapezium
  5. 4 equal sides and 4 right angles → square
  6. 2 pairs of equal sides next to each other, and no parallel sides → kite
  7. 2 pairs of parallel sides, no right angles and not all sides equal → parallelogram
  8. a triangle with 3 equal sides and 3 equal angles → equilateral triangle
  9. a triangle with one angle of 90° → right-angled triangle
  10. a triangle with exactly 2 equal sides → isosceles triangle
