Q1 of 805 Page 14

Draw ΔPOQ of measure 75° and find its line of symmetry.

Step 1: Draw an angle of 75 °s using a ruler and protractor



Step 2: With 0 as centre draw an arc to intersect OP and OQ at A and B



Step 3: With centre A and radius momre than AB draw an arc. With B as a centre and same radius draw another arc. Join O with the point of intersection.
