**Pythagoras Theorem**

** **

- What is Pythagoras Theorem
- Pythagoras Theorem applied to 2D shapes
- Pythagoras Theorem applied to 3D shapes

###### -

**Trigonometric Ratios**

- Right angle triangles
- Trigonometric Ratios (Sin / Cos / Tan) for right angle triangles
- Examples of working out sides and angles on a right angle triangle

###### -

**The Sine & Cosine Rules**

- Sine Rule (aka Law of Sines):
**a/(sin A)=b/(sin B)** - Cosine Rule (aka Law of Cosines):
**a²=b²+c²-2bcCosA** - Complement one another
- Used in non right angle triangles
- Sides and angles MUST be correctly named for the 2 rules to work

- Sine Rule (aka Law of Sines):
