Question

II. CONSTRUCT THE FOLLOWING ANGLES WITHOUT USING PROTRACTOR. (USE

SCALE AND COMPASS)


(i) 60º (ii) 120º​

Answer 1

Take base side AB
Draw an arc
With same dimensions cut it
First cut will give 60 degrees and 2nd cut will give 120 degrees angle

Answer 2

Answer:

Draw a line AB.

With A as centre and any radius cut an arc on line AB.

Keep the compass at the point of intersection of that arc on line AB and with the same radius ( taken for the first arc) cut another arc on the first arc . It gives you 60° .

Now from the 60° arc , cut another arc of same radius on the first arc, it gives you 120°.
