The corresponding angles in ABC and DEFR equal. If two triangles are similar, it means one can be mapped onto the other using a dilation and one or more rigid transformations. Both dilations and rigid transformations preserve all angle measurements. So, any combination of a dilation in a rigid transformation also preserve angle measures
