📖 1. Angles, bearings, and constructions

🔑 Key Concepts & Definitions

• Bearing : A bearing is a measurement of direction taken clockwise from the north direction to locate a point relative to another.
• Solving : Solving is the process of finding unknown values, such as angles or lengths, by applying geometric properties and relationships.
• Factorising : Factorising is the algebraic method of expressing an expression as a product of its factors, including single and double brackets.

📝 Essential Points

• Angles on a straight line sum to 180 degrees.
• Angles at a point sum to 360 degrees.
• The sum of angles in a triangle is 180 degrees.

💡 Key Takeaway

Angles on a straight line sum to 180 degrees.

📖 2. Fractions, ratios, and prime factorization

🔑 Key Concepts & Definitions

• Ratio : A comparison of two quantities expressed as a fraction, which can be simplified by dividing both terms by their highest common factor found through prime factorization.
• Product of primes : The result of multiplying prime numbers that compose a given number, used to find common factors and simplify ratios.
