Q3 of 805 Page 17

Using your protractor, draw an angle of measure 108°. With this angle as given, draw an angle of 54°.

The steps of the required construction are:

1) Draw an angle ∠BAC=108° using a protractor.



2) Taking B as the center draw an arc of any radius greater than . Now, Taking C as the center and the keeping the same radius, draw another arc, intersecting the previous arc at D. Join AD.
