Question

draw an angle of 4 5 degree using scale and compass only. draw the bisector of this

Answer 1

At first make a line then put the needle of compass on the starting and make a arc. Put the needle on the place where arc is meeting the line. Take the same measurement as arc and cut out the arc. Similarly draw the same by putting the compass on the 60 degree. Make a perpendicular bisector of 60 and 120 degree. It is 90 degree. Then take the needle on the starting point and bisect 90degee
It comes 45 degree.
