How to Find the Height of a Triangle. Two Methods: Using Base and Area Equilateral Triangle. To calculate the area of a triangle you need to know its height. If this information is not given to you, you can easily calculate it based on what you do know!This article will teach you two different ways to find the height of a triangle, depending on what information you have been given.Ad.ow to Find the Height of a Triangle.

Area of a Triangle: 1  If the length of the base and the height are known. 2  Area = Â½bh. 3  Where b is the length of the base and h is the height on the base. 4  If length of two sides and the angle between them are known. 5  Area = Â½xy sin(c) = Â½xz sin(a) = Â½yz sin(b). 6  Heron's formulaâif the length of the three sides are known. Pythagorean theoremâin any right triangle, the square of the length of the hypotenuse equals the sum of the squares of the lengths of the two other sides. 2  Conversely, if the lengths of the sides of a triangle satisfy the above condition, the angle opposite to the longest side is a right angle.
