About NCERT Solutions for Class 9 Maths Areas of Parallelograms and Triangles

You are already familiar with how to find areas of different two-dimensional shapes like a triangle, rectangle, square, etc. In this chapter, you will use that knowledge and study how to find the areas of these geometric figures under the condition when they lie on the same base and between the same parallels. Here are some important points related to Class 9 Maths Chapter 9 Areas of Parallelograms and Triangles:

  • A parallelogram is a quadrilateral with two pairs of parallel sides. 
  • The part of the plane enclosed by a simple closed figure is called a planar region corresponding to that figure. The magnitude or measure of this planar region is called its area
  • Two figures are called congruent if they have the same shape and the same size. 
  • If two figures are congruent, they have the same area. 
  • Two figures are said to be on the same base and between the same parallels, if they have a common base (side) and the vertices (or the vertex) opposite to the common base of each figure lie on a line parallel to the base.
  • Parallelograms on the same base (or equal bases) and between the same parallels are equal in area.
  • Parallelograms on the same base (or equal bases) and having equal areas lie between the same parallels.
  • If a parallelogram and a triangle are on the same base and between the same parallels, then the area of the triangle is half the area of the parallelogram.
  • Area of a parallelogram = Base X Height
  • Area of a triangle = ½ Base X Height
  • Triangles on the same base (or equal bases) and having equal areas lie between the same parallels.
  • A median of a triangle divides it into two triangles of equal areas.
