(TRIANGLES)

In order to calculate area of triangle, we can use any of the two

given methods, on the basis of the given conditions.

Method 1

When base of the triangle and corresponding height are given

1
Area of triangle = × × ℎ
2

(In case of right-angled triangle, adjacent sides containing right

angle are base and height respectively)
