WebSolution: Since all the sides of the given triangle are unequal in length, thus it is a scalene triangle. Using the formula for an altitude of a scalene triangle, we have; h = [2√ (s (s−a). (s−b). (s−c))]/b s = (a+b+c)/2 = (3+6+7)/2 = 16/2 = 8 h = [2√ (8 (8-3) (8-6) (8-7))]/2 h = [2√ (8.5.2.1)]/2 h = 4√5 Practice Questions WebIn a right triangle, (Hypotenuse) 2 = (Base) 2 + (Altitude) 2. The area of a right triangle is calculated using the formula, Area of a right triangle = 1/2 × base × height. The perimeter of a right triangle is the sum of the measures of all three sides. Isosceles right triangles have 90º, 45º, 45º as their angles.
