Scalene Triangle Equations These equations apply to any type of triangle. Click ‘Start Quiz’ to begin! area = sqrt(s * (s - a) * (s - b) * (s - c)) A scalene triangle is a triangle where all sides are unequal. \"h\" is the height (measured at right angles to the base)Area = ½ × b × hThe formula works for all triangles. Since the width is the 'base' of the triangle and the 'height' is the line that cuts through the original triangle and hits the base at a right angle, you can infer that the total rectange is base x height and that the area of the triangles is half that (remember, each one makes up half the rectangle around it, so they make up half total). Example: The sail on a sailboat is also likely to be raised in the shape of a scalene triangle, with no side of the sail being the same length as any other side. Use the area to find any of the altitude. Calculates the other elements of a scalene triangle from the selected elements.
