Label your triangle in the same way as you would using the Sine rule. Right triangles, and the relationships between their sides and angles, are the basis of trigonometry. Trigonometry: Right and Non-Right Triangles Area of a Triangle Using Sine We can use sine to determine the area of non-right triangles. Trigonometry is most simply associated with planar right-angle triangles (each of which is a two-dimensional triangle with one angle equal to 90 degrees). You need to know 2 sides and the angle in between. Sine Rule. This formula is derived from the area of a triangle formula, A=1/2Bh For any triangle ABC with side a opposite A, side b opposite B and side c opposite C, height h is represented This unit takes place in Term 5 of Year 10 and follows on from trigonometry with right-angled triangles.
