Trigonometry: Finding Missing Angles | SOH CAH TOA | GCSE Maths | Clarity Classrooms Welcome to Clarity Classrooms, where clarity builds confidence. In this full GCSE Maths lesson, Joanne explains how to use trigonometry to find missing angles in right-angled triangles. We'll look at how to identify the correct sides, choose the right trigonometric ratio and use the inverse trig functions on your calculator to find the missing angle. In this lesson, you'll learn: ✅ What SOH CAH TOA means ✅ How to identify the opposite, adjacent and hypotenuse ✅ How to choose between sine, cosine and tangent ✅ How to substitute the values into the correct ratio ✅ How to use inverse sine, cosine and tangent on your calculator ✅ How to find a missing angle step by step ✅ How to round your answer correctly ✅ Common mistakes to avoid in GCSE exams We'll start with straightforward examples before progressing to more challenging GCSE-style questions. 📚 This lesson is particularly useful for GCSE Maths students working towards Grades 4–5 and above. 📘 Clarity Classrooms We're building a complete catalogue of GCSE Maths lessons, with: Joanne – Foundation GCSE Maths (Grades 1–5) Liam – Higher GCSE Maths (Grades 5–9) 🎥 Subscribe to our YouTube channel:    / @clarityclassrooms   If you find this lesson useful, please like the video, subscribe to the channel and share it with another student who is revising GCSE Maths.
