Print only page 1
The students will answer questions on finding the missing angle using trigonometry. Once they have completed this there will be six 'extension' questions around the outside to complete, these are on finding a missing side. In the missing side questions all of the unknowns are in the numerator leading to easier rearranging.
Print pages 1-3
Students will answer questions on finding angles (page 1) and then have questions on finding missing sides where the unknown can be in either the numerator or denominator. Around the outside of the completed puzzle are triangles which can be used to generate some trigonometric ratios (30, 45 and 60 degrees)
I often give my students page 1 at first, and then after some additional lessons I give them pages 2 and 3 to complete the puzzle. Or will use page 1 as a quicker starter when revising trigonometry.
