## Steps to Find Area of a Triangle

The step by step workout for how to find what is the area of a triangle.__Workout :__

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

**Triangle**is 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.
