  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. p A B o 3. Put the compass on point o draw an arc and join the cut point and A. 60° p A B o

  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. p A B o 3. Put the compass on point o and draw an arc. p A B o

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

  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. p A B o 3. Put the compass on point o and draw an arc. p A B o

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

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

  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. p A B o 3. Put the compass on point o and draw an arc. p A B o

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

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

  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. p A B o 3. Put the compass on point o draw an arc. p A B o

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

  13. 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. T c m n P 45° o A B 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°
