You found one formula, area of △abc=(1/2)as sin b, that applies to an obtuse triangle just as it does to an acute triangle. which other formulas for the area of an obtuse triangle can you derive? show the formulas and justify your answer. using your own words, describe the formula for the area of an obtuse triangle in word form. based on the formulas for an acute triangle in task 1 and the formulas for an obtuse triangle in task 2, can you draw a general conclusion about the area formulas for any kind of triangle: acute, obtuse, or right?
