- The video explains how to use Pythagoras's theorem to find the missing length of a triangle.
- Pythagoras's theorem applies only to right-angled triangles.
- To use the theorem, you need:
  - A right angle in the triangle.
  - The lengths of two sides.
  - One missing length to find.
- The formula for Pythagoras's theorem is: \( a^2 + b^2 = c^2 \).
  - \( c \) is the hypotenuse (the longest side opposite the right angle).
  - \( a \) and \( b \) are the other two sides.
- Example 1:
  - Given sides: 3 and 4.
  - Calculation: \( 4^2 + 3^2 = c^2 \) simplifies to \( 25 = c^2 \).
  - Result: \( c = 5 \).
- Example 2:
  - Given sides: 1.7 and 3.2.
  - Calculation: \( 1.7^2 + 3.2^2 = x^2 \) simplifies to \( 13.13 = x^2 \).
  - Result: \( x \approx 3.62 \) (to three significant figures).
- Important to note:
  - Exam questions may label corners (e.g., x, y, z) and refer to sides by these labels.
- Example 3:
  - Find length xz.
  - Calculation: \( 5.6^2 + 10.5^2 = c^2 \) simplifies to \( 141.61 = c^2 \).
  - Result: \( c \approx 11.9 \).
- Example 4:
  - Find length ac.
  - Calculation: \( 8^2 + 11^2 = c^2 \) simplifies to \( 185 = c^2 \).
  - Result: \( c \approx 13.6 \).
