Class 9 Maths chapter 9 solutions pdf has a number of questions on area of triangle and area of parallelogram. Practice the solutions as many times as possible to master the chapter!
Area of Triangle:
A triangle has three sides which are joined to each other. A triangle in which of the angle is 90 degrees then it is called as right-angled triangle.
The area of a triangle can be given as the product of half the base and height. It can be represented as
Area= ½ b*h
Where b is base and h is height
There are different methods with which area can be calculated provided either base and height, length of the sides using Herons; formula, side-angle-side, equilateral triangle, two vectors from one vertex, etc, is given
Area of Parallelogram:
A parallelogram is a geometrical shape in which two sides of the quadrilateral are parallel to each other. The parallel lines are equal in length and the opposite angles of a parallelogram are equal to each other. Parallelogram is a flat shape is a flat shaped object. In a parallelogram opposite sides and the opposite angles are congruent to each other. The consecutive angles are supplementary. The area of a parallelogram can be given by the formula
A = b*h
A: Area of the parallelogram
