The area of a triangle can be calculated with the equation:

Triangle2

area = \frac {1}{2}\times base length \times perpendicular height

or Area1

However, this formula is only useful if the the base length and the perpendicular height to the base are known. There is another method for finding the area of a triangle if two side lengths are known (a and b) and the angle between them (C). (See Trigonometry for naming triangles). The formula is:

Area

These are the only two ways of finding the area of a triangle needed for GCSE or iGCSE, though there are many more (at least 7 ways in total!)
