### CBSE Class 10 Maths Chapter 7 Coordinate Geometry

- The position of a point P in the Cartesian plane with respect to coordinate axes is represented by the ordered pair (x, y).

- The line X’OX is called the X-axis and YOY’ is called the Y-axis.
- The part of the intersection of the X-axis and Y-axis is called the origin O and the coordinates of O are (0, 0).
- The perpendicular distance of a point P from the Y-axis is the ‘x’ coordinate and is called the abscissa.
- The perpendicular distance of a point P from the X-axis is the ‘y’ coordinate and is called the ordinate.
- Signs of abscissa and ordinate in different quadrants are as given in the diagram:

- Any point on the X-axis is of the form (x, 0).
- Any point on the Y-axis is of the form (0, y).
- The distance between two points P(x1, y1) and Q (x2, y2) is given by

PQ = (x2−x1)2+(y2−y1)2−−−−−−−−−−−−−−−−−−√

Note. If O is the origin, the distance of a point P(x, y) from the origin O(0, 0) is given by

OP = x2+y2−−−−−−√

PQ =

Note. If O is the origin, the distance of a point P(x, y) from the origin O(0, 0) is given by

OP =

Section formula. The coordinates of the point which divides the line segment joining the points A(x1, y1) and B(x2, y2) internally in the ratio m : n are:

The above formula is a section formula. The ratio m: n can also be written as

co-ordinates of P can also be written as P(x,y) =

The mid-point of the line segment joining the points P(x1, y1) and Q(x2, y2) is

Here m : n = 1 :1.

Area of a Triangle. The area of a triangle formed by points A(x1 y1), B(x2, y2) and C(x3, y3) is given by | ∆ |,

where ∆ =

where ∆ represents the absolute value.

- Three points are collinear if |A| = 0.
- If P is the centroid of a triangle then the median divides it in the ratio 2 :1. Co-ordinates of P are given by
P=(x1+x2+x33,y1+y2+y33)

Area of a quadrilateral, ABCD = ar(∆ABC) + ar(∆ADC)
