Using a rule and a pair of compass only construct ∆|AB|=18CM,<CBA=45°and <CAB=60°

Question

(i) Construct the bisector of angle of ACB to meet AB

Answer 1

How do you expect us to show you how on this webpage?

there are many sites that describe how your construction is done, just
google it.
btw, constructing angles of 60° and 45° are fundamental to this
topic and should be found in your text or your notes from class.
