Triangle area activity

A challenging activity on the theme of triangle area, suitable for year 11 revision.

The initial questions require a knowledge of basic triangle area, Pythagoras’ theorem, SOHCAHTOA, the sine rule and 1/2absinC so a good, challenging revision task.

The questions have been designed with a ‘minimally diferent’ element, to draw pupils attention to how subtle changes can have significant implications for selecting methods.

There are some follow-up questions, that could be used to shift the focus of the activity.

I’d love to hear anyone’s suggestions of further questions.
