Trigonometry perimeters:Code breaker
Thirteen diagrams, each with one angle and one side. Find the other sides with trigonometry or Pythagoras and add them up. The angle moves round the triangle, and the last two hide the right-angled triangle in an isosceles triangle and a rectangle. A usual slip still unlocks a letter. One per A4.
A free key stage 3 and GCSE geometry and measures puzzle with answers, spec code G20. It goes with the lesson on trigonometry: missing sides, mixed.
