In this section, you will learn how to construct angles using protractor.

To construct an angle using protractor, we must need the following mathematical instruments.

1. Ruler

2. Protractor

**Example 1 :**

Construct an acute angle of 60°.

**Step 1 :**

Draw a line segment PA.

**Step 2 :**

(i) Place the protractor on the line segment PA

(ii) Place the mid point of the protractor at point P as shown in the figure.

**Step 3 :**

(i) On PA from the right start counting from 0° in the ascending order (counter clock wise direction and finally mark a point Q using a sharp pencil at the point showing 60° on the semi-circular edge of the protractor.

(ii) Remove the protractor and join PQ.

(iii) We get the required angle ∠APQ = 60°.

**Example 2 :**

Construct an acute angle of 125°.

**Step 1 :**

Draw a line segment PA.

**Step 2 :**

(i) Place the protractor on the line segment PA.

(ii) Place the mid point of the protractor at point P as shown in the figure.

**Step 3 :**

(i) On PA from the right start counting from 0° in the ascending order (counter clock wise direction ) and finally mark a point Q using a sharp pencil at the point between 120° and 130° showing 125° on the semicircular edge of the protractor.

(ii) Remove the protractor and join PQ.

(iii) We get the required angle ∠APQ = 125°.

Apart from using protractor, we can construct angles using ruler and compass also.
