How do you construct a 112.5 degree angle? (step by step) Please help =)

Question

anonymous · Answer

First break it down into its components. For example a 90 degree + (half a 45 degree)

anonymous · Answer

Wow thanks for your help but i am not understanding .-.

anonymous · Answer

You can draw a 90 degree by drawing two 60 degrees on top of eachother, then halving one of them gives (60+60/2)=90

anonymous · Answer

I know how to construct a 90 degree angle, i am just having a problem with the construction of a 112.5 degree angle. I really appreciate that you are helping me.
