Congruence shares properties with algebraic equality: transitivity (if A ≅ B and B ≅ C, then A ≅ C), reflexivity (things equal themselves: A ≅ A, and symmetry (A ≅ B is the same as B ≅ A).

## Is congruent and equal are same?

If some attributes of geometric figures are the same in magnitude, then they are said to be equal. **If both the sizes and the figures are equal, then** the figures are said to be congruent. Equality concerns the magnitude (numbers) while congruence concerns both the shape and the size of a figure.

## Are angles congruent or equal?
