KS4. Geometry. Angles & Symmetry. Alternate & Corresponding Angles

We need to remember the relationships between the angles that a transversal makes when it crosses a pair of parallel lines:

We also need to know their names, so we need to know what are;

  • vertically opposite angles;
  • corresponding angles;
  • alternate angles; and
