Chapter 9- Areas of parallelograms and triangles
Master the concept of Areas of parallelograms and triangles!
An ‘area’ in maths refers to the space inside the boundary of a 2D figure. The formula of the area varies from figure to figure. Like in a parallelogram, the main components are base and height and same in the triangle, but the area of a triangle with same base and height as parallelogram is half of parallelogram.
We, at ScoreX™, help you to comprehend the topic in such a simple and unique style. We provide a full course of Class 9 Maths Ch-9 Areas of Parallelograms and Triangles.
What is the structure of the course?
We almost cover everything related to the chapter in our course of CBSE class 9 Maths chapter 9. Main topics we cover are: -
1. Figures on the same base and between the same parallels-
This is a theorem which states that area of figures on the same base and the same parallel lines are always equal or vice versa.
2. Triangles on the same base and between the same parallels-
This theorem states that triangles on the same base and having equal areas lies between the same parallel or vice versa.
3. Parallelograms on the same base and between the same parallels-
This theorem states that parallelogram which lies between same parallels and has equal areas lie on the same base.
4. Two congruent figures have equal areas-
The figures can be congruent by different criteria like SSS, ASA, SAS, and RHS. The congruent figures will always have equal areas.
