You could measure each of the point. but for 80°, 140°, 160° .... are not divisible by 15° so we can't draw it accurately with help of compass that's why we have protector. Step 1 : Draw a line ‘l’ and mark a point ‘O’ on it. Start by drawing a horizontal line and marking the left end “A” and the right end “B” to serve as the vertex of the angle. (ii) We get the required angle ∠ AOB = 60°. Step two - make angle of 60 & 120 with compass Step three - bisect angles of 60 & 120 to get 90 degree angle Step four - bisect angles of 90 & 120 FINALL YOU WILL GET THE ANGLE OF 105 DEGREE as difference between 90&120 is 30 we bisect it so it is 15 which is added to 90 to get 105 degree angle Brainly User Brainly User I have drawn above hope it helps you New … The angle measuring 100° cannot be constructed directly with compass as it is not the multiple of 15 only the angle which are multiples of 15 can be constructed directly with the help of compass. figure shows angle of 160° drawn by compass.
