Question:
Using a protractor, draw each of the following angles.
$430^{\circ}$
Solution:
The given angle is greater than 360°
Adding or subtracting $360^{\circ}$ from a particular angle does'nt changes its position.
Therefore, Angle can also be written at as $=430^{\circ}-360^{\circ}=70^{\circ}$
- Draw a straight line AB.
- Place a dot at B. This dot represents the vertex of the angle.
- Place the centre of the protractor at B and the baseline of the protractor along the arm BA.
- Find $70^{\circ}$ on the scale and mark a small dot at the edge of the protractor.
- Join the vertex $B$ to the small dot with a ruler to form the second arm, $B C$, of the angle.
- Mark the angle with a small arc as shown below.
