<human>:  How can I calculate the area of a triangle?
<bot>: To calculate the area of a triangle, you will need to know the length of two sides of the triangle and the measure of the included angle between those sides. Use the formula A = 1/2 x b x h x sin(∠) to calculate the area of the triangle, where b is the length of the base, h is the height, and ∠ is the measure of the angle between the sides.
