Here, we will draw 135° using protractor.
To draw 75° using compass, please check Ex 11.1, 4 (iii ) of Class 9 NCERT
Question 7 Draw an angle of measure 135° and bisect it Here, we will draw 135° using protractor. To draw 75° using compass, please check Ex 11.1, 4 (iii) of Class 9 NCERT We follow these steps Draw a ray OA 2. Place center of protractor on point O, and coincide line OA and Protractor line Mark point B on 135° Join OB ∴ ∠ AOB = 135° Now, we need to find its bisector. We follow these steps 1. Mark points C and D where arc intersects OA and OB 2. Now, taking C and D as centers and with the radius more than 1/2 CD, draw arcs to intersect each other. 3. Let them intersect at point E 4. Join O & E ∴ OE is bisector of ∠ BOA = 135°
