1. Learn to draw Angles using compass

2. 60° Angle 1. Draw a line segment AB with the help of scale. A B 2. Make an arc with the help of a compass at point A. A B 3. Put the compass on point o draw an arc and join the cut point and A. A B o p o p 60°

3. 120° Angle 1. Draw a line segment AB with the help of scale. A B 2. Make an arc with the help of a compass at point A. A B 3. Put the compass on point o and draw an arc. A B o p o p

4. 4. Put the compass on the first cut and draw another arc and join the cut point and point A. 120° A B p o c C AB= 120°

5. 180°(Straight) Angle 1. Draw a line segment AB with the help of scale. A B 2. Make an arc with the help of a compass at point A. A B 3. Put the compass on point o and draw an arc. A B o p o p

6. 4. Put the compass on the first cut and draw another arc and then from point c draw one more arc. A B p o c

7. 4. Join QA. A B p o c Q 180° QAB= 180°

8. 90°(Right) Angle 1. Draw a line segment AB with the help of scale. A B 2. Make an arc with the help of a compass at point A. A B 3. Put the compass on point o and draw an arc. A B o p o p

9. 4. Put the compass on the point m and c respectively and cut the arcs from both the points. A B o c m T

10. 4. Join TA. A B o c m T 90° TAB= 90°

11. 30° Angle 1. Draw a line segment AB with the help of scale. A B 2. Make an arc with the help of a compass at point A. A B 3. Put the compass on point o draw an arc. A B o p o p

12. 4.Put the compass on point o and n respectively draw arcs from both the sides. And join the he generated point to A. A B op n M 30° MAB = 30°

13. A B o c m T 45° Angle 1 Draw the angle of 90° as learned before. Draw arcs from point n and o respectively and join the cut point to A. nP 45° It is very simple to draw the angle of 45°. We just bisect the angle of 90°.

14. We have learnt all the major angles and how to draw remaining ones. TIPS for the remaining ones are here. For 75°, cut an arc from 60° and another one from 90°. You will get the desired angle. For 105°, cut the arcs from 90° and 120°. For 150°, use 120° and 180° likewise For 115°,you need to choose 120° and 150°
