Geometrical Constructions: Class 9: Angle 30°..

Geometrical Constructions:
Class: 9
Angle: 30°
Steps:
1. Draw a Ray AB of any length(Say 7 cm).
2. Take more than half of radius from AB draw an arc which meets the ray AB.
Therefore arc it touches on AB ..Mark it as X.
3. Take same radius with centre X draw an arc Mark it as Y ..draw a Ray AY ..extend ...
4. With centre X draw an arc and with centre Y cut an arc ...Mark it as W.
Join AW. ( Bisectors)
5. Therefore WAB or ZAW is 30°
