Question

$construct \: the \: following \: angles \: and \: verify \: by \: measuring \: them \: by \: a \: protector \: . \: \: (i)75 degree \: (ii)105 \: degree \: (iii )135 \: degree .$
Help me please...
​

Answer 1

do one thing construct it by compass and then measure it by protector.

75= make angle of 60 by compass then 90 by again compass and then bysect the angle between 90 and 60.

2. 105 = make angle of 90 then 120 then bisect the angle between 90 and 120 .

3 . 135=. make angle of 120 then 180 then bisect the angle between 120 and 180 then you will get angle of 135.
