Draw an angle of 70 degree. Make a copy of it using only a straight edge and compass.(3 Mark)
To construct an angle of measure 700 and its copy listed below are the steps that are to be followed
(i) Draw a line l and mark a point O on it. Now place the centre of protractor at point O and the zero edge along line l.
(ii) Locate a point A at an angle of measure 700. Join OA. Now OA is the ray making 700 with line l. With point O as centre, draw an arc of convenient radius in the interior of 700 angle. Let this intersects both rays of angle 700 at points B and C respectively
(iii) Draw a line m and mark a point P on it. Again draw an arc with same radius as before and P as centre. Let it cut the line m at point D
(iv) Adjust the compasses up to the length of BC. With this radius draw an arc taking D as centre which intersects the previously drawn arc at point E.
(v) Join PE. Here PE is the required ray which makes same angle of measure 700 with the line m
