1.3 Angles

Introduction

Remember from year 7 the principles of:

  • Measuring angles
  • Angles on a straight line
  • Vertically opposite
  • Parallel lines and Corresponding angles
  • Alternate angles

In addition, you should be aware of co-interior angles. For example, in the angles:

Examples of co-interior angles are d and f, which add up to 180\textdegree.
