Concept
(1)
Using the standard formula for the area of a triangle, we can derive a formula for using sine to calculate the area of a triangle. Using sine to calculate the area of a triangle means that we can find the area knowing only the measures of two sides and an angle of the triangle. There is no need to know the height of the triangle, only how to calculate using the sine function.
