(4) (5) (6) It is conventional to label You can draw in the You can find an expression for triangles like this: C perpendicular height on any the perpendicular height: triangle: sin 0 = - Opp b Hyp sin A = This can be rearranged to give: Notice how the sides opposite the angles use the CD = b sin A same letter, just lower case. This now gives us two (So height = CD = b sin A ) angled triangles.E V > docs.google.com + 88 Headrush - Module - 06 Geometry: Non-... Copy of Developing Area of Triangle Usin.

Area = nearest tenth: Area = 1/2 base x height Area = 1/2 ab sin C 7 cm Area = 1/2 X AB x CD Area = 1/2 ac sin B Area = 1/2 X CX A
