📌 1. Trigonometry kya hai?
Trigonometry math ki ek branch hai jo triangles ke angles aur sides ke beech relation ko study
📌
karti hai.
2. Right Angled Triangle
👉
Trigonometry sirf 90° wale triangle par apply hoti hai.
Is triangle mein 3 sides hoti hain:
Hypotenuse (sab se lambi side)
Opposite side
📌
Adjacent side
3. Basic Trigonometric Ratios

4. Easy Trick to Remember (SOH-CAH-TOA)
✔ SOH → sin = Opposite / Hypotenuse
✔ CAH → cos = Adjacent / Hypotenuse
📌
✔ TOA → tan = Opposite / Adjacent
👉
5. Example
✅
If opposite = 3 and hypotenuse = 5
📌 💡
sin θ = 3/5 = 0.6

7. Practice Questions
sin θ = ? (Opposite = 4, Hypotenuse = 8)
cos θ = ? (Adjacent = 6, Hypotenuse = 10)
📌 🎯
tan θ = ? (Opposite = 5, Adjacent = 5)
8. Important Tips
✔ SOH-CAH-TOA yaad rakho
✔ Triangle diagram practice karo
