Draw a straight line then construct 60 then 120 and then 90 once you have done these bisect these angles and you will be able to find another three angles so to construct all angles you will have to bisect every angle that you construct

Take a compass with protractor ,measure the protractor with scale and take the measurement in the compass . Take a card board sheet and now draw the circle and put the protractor on the circle now draw the diameter . or with protractor only we can draw semi circle or full circle . or draw a line of 5 cm and take 4cm and from the point draw an arc up to near to the line now extended the and see it . it form a 180 * it is equal to a semi circle protractor .
