Interactive Quiz: Test Your SOH CAH TOA Knowledge

📚 Quick Study Guide

• 📐 SOH: Sine = Opposite / Hypotenuse
• 📏 CAH: Cosine = Adjacent / Hypotenuse
• ✏️ TOA: Tangent = Opposite / Adjacent
• 💡Remember these ratios are used for right-angled triangles only!
• 🧮 The Hypotenuse is always the longest side, opposite the right angle.
• ➕ Opposite and Adjacent sides depend on the angle you are referencing.
• ➗ Use these ratios to find missing angles or sides of right triangles.
