To find the height of a scalene triangle, the formula for the area of a triangle is necessary. The equation is area = 1/2hb, where h is the height and b is the base. However, before using this formula, other calculations are required.
Know MoreA scalene triangle has three sides that are unequal in length, and the three angles are also unequal. To find the height of a scalene triangle, the three sides must be given, so that the area can also be found. If a scalene triangle has three side lengths given as A, B and C, the area is given using Heron's formula, which is area = square root{S (S - A)x(S - B) x (S - C)}, where S represents half the sum of the three sides or 1/2(A+ B+ C).
To find the height h from the given triangle area formula, rearrange it as h = 2(area)/b. Let b equal the side length B and find the area A with Heron's formula. In triangles, the measurement for height is given at 90 degrees to the base.
Learn more about GeometryA real-life example of a scalene triangle is a roof truss as used in the building roofs on houses and buildings. Other examples include ramps and sails. A scalene triangle is defined as a triangle with no equal sides and no three angles the same.
Full Answer >The recursive formula for Sierpinski triangle is An=An-1*3. The procedure of constructing the triangle with this formula is called recursion. Alternatively, the Sierpinski triangle can be created using the explicit formula An=1*3(n-1), where (n-1) is the exponent.
Full Answer >The formula for calculating the length of one side of a right-angled triangle when the length of the other two sides is known is a^{2} + b^{2} = c^{2}. This is known as the Pythagorean theorem.
Full Answer >The area of a parallelogram can be calculated by multiplying the length of the base by the height to the top, perpendicular to the base. Either edge on either set of sides can be oriented to be the base. The formula for a parallelogram's area is similar to that of a rectangle, because a rectangle is a special type of parallelogram.
