Steps to Find Area of a Triangle
The step by step workout for how to find what is the area of a triangle.
step1 Address the formula, input parameters and values
Base = 10 in
Height = 5 in
step 2 Find Area of triangle using base and height values
Area A = bh/2
= (10 x 5)/2 in²
= 50/2 in²
Area A = 25 in²
Definition & Formula
Triangleis a two dimensional plane or geometric shape with three straight sides and three angles. In other words, it's a polygon with three edges and three vertices. The sum of three angles in a triangle is always equal to 180 degrees (180º). There are different types of triangle such as Equilateral, Isosceles, Scalene, Acute, Obtuse and Right Angle Triangle. A triangle with three equal length of sides called an equilateral triangle, whereas an isosceles consists of two sides of equal length.
