Preparing for A-Level Physics
Listed below are some tasks that we would like you to do before you come back in
September. Please do them to the best of your ability. You will need to bring them to your
first lesson in September as you will be using some of them in the lesson!

Triangles in Physics (Trigonometry and Pythagoras)
You will be very familiar with trigonometry and Pythagoras’ theorem from GCSE maths! In A-level
Physics, they also play a large part.
1. Find x and H in the right-angled triangle below.
2. Find the lengths of all sides of the right-angled triangle below if its area is 400cm2.
3. BH is perpendicular to AC. Find x, the length of BC.
4, ABC is a right-angled triangle with a right angle at A. Find x the length of DC.
5. Find the length of segment BD.
