Class 10 Maths Chapter 7 Coordinate Geometry: Important Topics
The important topics of chapter 7 coodinate geometry are given below:
- Distance Formula – In coordinate geometry, distance formula is used to find the distance between two points in a coordinate plane. It is derived with the help of Pythagoras theorem.
Distance formula, for two points say P and Q with coordinates (x1,y1) and (x2,y2) respectively, is given by; \(PQ = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\) |
- Section Formula – Section formula is used to find the coordinates of the point that divides a line segment into two ratios.
Section formula, for a point P dividing a line segment AB with A (x1,y1) and B (x2,y2) in the ratio m1:m2 , is given by; \(P(x,y) = (\frac{m_1x_2 + m_2x_1}{m_1 + m_2} , \frac{m_1y_2 + m_2y_1}{m_1 + m_2})\) |
- Area of a Triangle – Area of a Triangle can be calculated when coordinates of the vertices of the triangle are given.
The formula for calculating area of a triangle ABC with vertices A (x1,y1), B (x2,y2) and C (x3,y3) is given by; \(Area = \frac{1}{2} [x_1(y_2 - y_3) + x_2(y_3 - y_1) + x_3(y_1 - y_2)]\) |
