Triangle a b c is shown. The length of b c is a, the length of a c is b, and the length of a b is c. Auxiliary lines are added from point b to point d and point c to point d to form a right angle. See the figure of δabc with auxiliary lines added. If c is the base of δabc, the height is. Sin(a) =. The previous statement is leading to the derivation of which area formula? area δabc =.
