Yes

Explanation:

Rigorous definition of congruence assumes the possibility to transform one object into another using rigid transformations of translation (shift), rotation and reflection (relatively to a straight line).

One right angle can be transformed into another using these transformations. Therefore, any two right angles are congruent.
