we learnt that the angle of incidence=to the angle of question is that sir when we form the ray diagram of a concave mirror ie when the object is at focus then won't the angle of incidence and the angle of reflection be different?

When the object is located at the focal point, there is no location in space at which an observer can sight from which all the reflected rays appear to be diverging. An image is not formed when the object is located at the focal point of a concave mirror.
Angle of incidence is same as angle of reflection
