##### 1 Answer

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.
