Area of a triangle

A triangle is a polygon with three corners or vertices and three sides which are line segments.A triangle with three vertices A, B and C are written as ABC .


Let's see how to calculate the area of a triangle.
Area of a triangle formula is given as:
1/2b x h , where b is the base and h is the height of the triangle.


Let us take an example. Suppose, we have a ABC whose base is 3cm, height - 5cm, 
then, by using the formula Area of a triangle = 1/2b x h ,

we can write Area of the triangle = 1/2 x 3 x 5 = 15/2 = 7.5 sq.unit.

There are different ways to calculate the area of a triangle according to the types of triangle.We will learn 
the different ways next time.
