Results of the SND experiment at the VEPP-2M e+e- collider on the QED processes e+e- → e+e-γ and e+e- → e+e-γγ with production at large angles are presented. The energy and angular distributions of the final particles were studied. No deviations from QED were found, with an accuracy of 3.8% for the first process and 10.3% for the second.
