What is this resource?

The Trigonometry Missing Sides Homework resource acts as a fantastic supporting document that can be used to reinforce learning outside of the classroom. The pupils are tasked with working out the length of missing sides on right-angled triangles. Our Trigonometry Missing Sides Homework provides clear descriptions in addition to a series of tasks that are designed to instil confidence within the KS4 Maths pupil.

How does the Trigonometry Missing Sides Homework help KS4 Maths learners to reinforce their learning?

The homework piece provides an excellent introductory explanation to ease the KS4 Maths learner into a series of carefully written questions. The core aim of the Trigonometry Missing Sides resource is to build the pupil’s confidence and competence in dealing with sin, cos and tan as part of calculating missing lengths on a right-angled triangle.

Home Learning

This resource is ideal for working through as a home learning worksheet. The nature of the design means that it can be completed independently or with some light guidance. As all answers are included at the end of the resource, it puts the learner in a position whereby they are able to self-check their work. If you have no option of printing out at home, then this home learning resource can also be worked through as an on-screen document. The pupil can write the answers on some spare paper (or a notebook) and check them once completed.

What is SOHCAHTOA?

SOHCAHTOA is a mnemonic that is used to remember which function to use when calculating lengths of specific sides in right-angled triangles.
• SOH = Sine equals opposite over hypotenuse
• CAH = Cosine equals adjacent over hypotenuse
• TOA = Tangent equals opposite over adjacent

Beyond’s Trigonometry Missing Sides Homework resource centres on this area of trigonometry and provides an excellent classroom companion to help reinforcement of learning at KS4 Maths level.
