About this lesson
This video is another in the series for Year 9 relating to Pythagoras' Theorem and Trigonometry. Almost at the end of this series, this video looks at applying all the learning from the previous videos to some worded problems. I know not many people like worded problems, but the ones in this video are the "more likely" to be used in exams and tests and highlight the many ways the questions can be asked. So long as you can find the right angled triangle and understand Elevation and Depression, you're going to smash this part of the course. There are lots of worked examples which are used to explain the theory which is delivered in an easy to understand way.
