What you need to know:
A very common type of question involves finding angles formed with parallel lines. These are problems involving angles colloquially referred to as “F angles” and “Z angles” because the shapes that the lines form often resemble the shapes of the letters F and Z. However, these are colloquial terms and cannot be used in an exam to explain your working in a question on this topic. Instead, you should understand how and when you use the following facts:
- Angles around a point add up to 360 \degree;
- Angles on a straight line add up to 180 \degree;
- Corresponding angles are equal (often called “F angles”);
- Vertically opposite angles are equal;
- Alternate angles are equal (often called “Z angles”);
- Interior angles add up to 180 \degree.
You may find that many of these facts listed are obvious if you are looking at a picture of them, however it is important to know which facts you are applying and when, as the question could (and probably will) ask you to explain how you obtained the value of a particular angle.
