A 0.88Mev photon is scattered by a free electron initially at rest such that the scattering angle of the scattered electron is equal to the scattered photon.How to find the angle??

This is a beginning. To get background information got to
http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/comptint.html
Once there, read about Compton scattering and be sure to click the link "Develop formula" This should get you started about what is going. If you still have questions, do come back.
