How is the reflection of light ray from a plane mirror different from the refraction of light ray as it enters a block of glass?

In the case of reflection, the angle of reflection is equal to the angle of incidence $(\angle i=\angle r)$.

On the other hand, in the case of refraction, the angle of refraction is not equal to the angle of incidence $(\angle i$≠$\angle r)$.
