Tamil Nadu Board Solutions for Chapter: Coordinate Geometry, Exercise 1: Exercise

Write down the abscissa and ordinate of $R$

Write down the abscissa and ordinate of Point $\mathrm{S}$.

Plot the following points in the coordinate plane and join them. What is your conclusion about the resulting figure?

$\left(-5,3\right) \left(-1,3\right) \left(0,3\right) \left(5,3\right)$

Plot the following points in the coordinate plane and join them. What is your conclusion about the resulting figure?

$\left(0,-4\right) \left(0,-2\right) \left(0,4\right) \left(0,5\right)$

Plot $\left(0,0\right) \left(-4,0\right) \left(-4,-4\right) \left(0,-4\right)$ in the coordinate plane. Join them in order. What is the name of the geometrical shape is formed?

Plot $\left(-3,3\right) \left(2,3\right) \left(-6,-1\right) \left(5,-1\right)$ in the coordinate plane. Join them in order. What is the name of the geometrical shape is formed?

In which quadrant does the following points lie?

(a) $\left(3, -8\right)$

(b) $\left(-1, -3\right)$

(c) $\left(2, 5\right)$

(d) $\left(-7, 3\right)$

Let $A\left(2, 2\right), B\left(8, -4\right)$ be two given points in a plane. If a point $P$ lies on the $X$- axis (in positive side), and divides $AB$ in the ratio $1:2$, then find the coordinates of $P$.
