Results of the SND experiment at the VEPP-2M \(e^+e^-\) collider on the QED processes \(e^+e^-\rightarrow e^+e^-\gamma\) and \(e^+e^-\rightarrow e^+e^-\gamma\gamma\) 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.
