Suppose we have two angles

∠ ABC and ∠ PQR




Two angles are congruent if

  • They have same shape
  • They have same size


  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



  Two angles are congruent if they have the same value .
