##### Construction of Angles of Special Measures

There are some elegant and accurate methods to construct some angles of special sizes without the use

##### I. To Construct an Angle of 60Â°

We take the following steps for this construction:

- Draw a ray BC.
- With B as centre and any suitable radius draw an arc above BC cutting BC at R.
- With R as centre and same radius cut the arc at S.
- Join BS and produce it to A.
- Then angle ABC is the required angle of 60Â°.

##### II. To construct an Angle of 30Â°

Observe that 30Â° = Â½ Ã— 60Â°.

We therefore, follow the procedure of bisecting a given angle learnt in previous section to get the required angle. Thus, to construct an angle of 30Â°, we proceed as follows:

Step-1: Draw an angle ABC = 60Â° as done above.

Step-2: Bisect angle ABC.

Step-3: Then angle RBC = 30Â° and also angle ABR = 30Â°.

##### III. To Construct an Angle of 90Â°

We take the following steps for this construction:

- Draw a ray BC.
- With B as centre and any suitable radius draw an arc cutting BC at D.
- With D as centre and same radius cut the arc at E and then with E as centre and the same radius cut the arc again at F.
- With E and F as centres and any suitable radius draw arcs cutting each other at P.
- Join BP and produce to A. Then angle ABC is the required angle, i.e., 90Â°.

##### IV. To Construct an Angle of 45Â°

We take the following steps for this construction:

(i) Draw an angle ABC = 90Â°.

(ii) With D as centre and radius more than half of DE draw an arc.

(iii) With G as centre and same radius as above, draw another arc cutting the first arc at H.

(iv) Join BH and produce to M.

Then angle CBM is the required angle of 45Â° and also angle MBA is 45Â°.

### Class 6 Maths Exercise 14.6 Important Questions

### What are the types of angles?

Different Types of Angles:

(i) Zero Angles.

(ii)Acute Angles.

(iii)Right Angles.

(iv)Obtuse Angles.

(v)Straight Angles.

(vi)Reflex Angles.

(vii)Complete Angle.

### What are standard angles?

Trigonometric ratios are Sine, Cosine, Tangent, Cotangent, Secant and Cosecant. The standard angles for these trigonometric ratios are 0Â°, 30Â°, 45Â°, 60Â° and 90Â°. These angles are most commonly and frequently used in trigonometry.

### How do you construct a 120 angle?

Constructing a 120Â° Angle: 120Â° angle can be constructed using the logic that 60Â° + 120Â° = 180Â°. Thus, we can understand that in order to construct 120Â° we can construct 60Â° angle and then further extend one of its arms.

##### V. To Construct an Angle of 120Â°

We take the following steps for this construction:

Step-1: Draw a ray BC.

Step-2: With B as centre and any suitable radius draw an arc cutting BC at D.

Step-3: With D as centre and same radius cut off the arc first at E and then with E as centre cut off the arc at another point F.

Step-4: Join BF and produce it to A. then angle ABC is the required angle of 120Â°.
