Question: how to find the height of a triangle angles?
Answer: A right triangle is a triangle with one angle equal to 90°. Two heights are easy to find, as the legs are perpendicular: if the shorter leg is a base, then the longer leg is the altitude (and the other way round). The third altitude of a triangle may be calculated from the formula: hᶜ = area * 2 / c = a * b / c.
