An angle construction...

[Pinaki Biswas]

From a given point P draw a straight line 'a' which contains point P making with another given straight line 'b' an angle of given magnitude.

[Sankhadip Chakraborty]

Take any point \(Q\) on \(b\). Through \(Q\), draw a line \(a'\) which makes the given angle with \(b\). Now draw a parallel to \(a'\) through \(P\). This is our required \(a\).
