∠ ABC and ∠ PQR

Two angles are congruent if

  • They have same shape
  • They have same size

Now,

  All angles of same value will have same shape.

 

For example:

∠ABC and ∠PQR have

  • Same shape - both are angles
  • Same size - Both are 30°

So, they are congruent

 

So, Angles with same values are congruent

 

Therefore,

  Two angles are congruent if they have the same value .
