Some dimensions (in metres) are indicated on the figure. Trigonometry was developed in ancient civilisations to solve practical problems, such as those encountered in building construction and when navigating by the stars. To VERIFY AN IDENTITY: Work on each side separately and make sure you don’t move things from one side to the other! You can work on both sides at the same time – but you just can’t move things gonometry Identities Grade 11 Ma. • Sta.
