Area of a Triangle with Pythagoras and Trigonometry

A set of ‘increasingly difficult’ questions to first recap finding the area of a triangle and then blend this with a revision of Pythagoras’ Theorem and right-angled trigonometry. The last few questions could be used as a lead-in to introducing or deriving the general formula for the area of a triangle given two sides and the included angle. Answers are included on the second page.
