**(iii) R **

**(iv) S**

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

**(i) (–5,3) (–1,3) (0,3) (5,3)**** **

**(ii) (0,–4) (0,–2) (0,4) (0,5)**

**4. Plot the following points in the coordinate
plane. Join them in order. What type of geometrical shape is formed?**

**(i) (0,0) (–4,0) (–4,–4) (0,–4)**

**(ii) (–3,3) (2,3) (–6,–1) (5,–1)**

**Activity – 1**

Plot the following points on a graph sheet by taking the scale as
1cm = 1 unit.

Find how far the points are from each other?

A (1, 0) and D (4, 0). Find AD and also DA.

Is *AD = DA*?

You plot another set of points and verify your Result.
