Mensuration - Area and perimeter of triangles

Triangles
Tri means three. Hence tri- angle means three angled figure. For construction of three angled figure, there should
be three sides. Hence triangle means three sided figure. Sum of the three angles of any triangle = 180º.
i Any triangle.

Area of any triangle = x Base x Height unit²

ii Isosceles Triangle
