(i) Step 1: Draw a line AB.

Step 2: Place the baseline of the protractor along BA and make sure centre of the protractor lie at point B.

Step 3: Find 60° on the scale of the protractor and mark a small dot at the edge and named as P as shown below:

Step 4: Join P to B with a ruler to form the second arm, BP, of the angle.

Mark the angle with a small arc as shown below:

(ii) Step 1: Draw a line AB.

Step 2: Place the baseline of the protractor along BA and make sure centre of the protractor lie at point B.

Step 3: Find 130° on the scale of the protractor and mark a small dot at the edge and named as C as shown below:

Step 4: Join C to B with a ruler to form the second arm, BC, of the angle.

Mark the angle with a small arc as shown below:

(iii) Step 1: Draw a line AB.

Step 2: Place the baseline of the protractor along BA and make sure centre of the protractor lie at point B.

Step 3: Find 300° on the scale of the protractor and mark a small dot at the edge and named as C as shown below:

Step 4: Join C to B with a ruler to form the second arm, BC, of the angle.

Mark the angle with a small arc as shown below:

(iv) We know, adding or subtracting 360° from a particular angle does not changes its position.

Therefore, given angle can also be written as:

430° – 360° = 70°

Now, we have to draw an angle for 70°

Step 1: Draw a line AB.

Step 2: Place the baseline of the protractor along BA and make sure centre of the protractor lie at point B.

Step 3: Find 430° on the scale of the protractor and mark a small dot at the edge and named as C as shown below:

Step 4: Join C to B with a ruler to form the second arm, BC, of the angle.

Mark the angle with a small arc as shown below:
