Q4 of 805 Page 17

Using protractor, draw a right angle. Bisect it to get an angle of measure 45°.

The steps of the required construction are:

1) Draw an angle ∠BAC=90° 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.
