What to Focus On

  • Congruent figures match exactly in shape and size.
  • Two lines are congruent only if their lengths are equal.
  • The symbols for congruency are = and ≡.

  • Congruent triangles match exactly in size and shape.
  • In triangle ABC and triangle DEF, A matches D, B matches E and C matches F.
  • Corresponding sides are AB-DE, BC-EF and AC-DF.

  • S.S.S. uses three equal sides.
  • S.A.S. uses two equal sides and the included angle.
  • A.S.A. uses two equal angles and the included side.

Common Mistakes to Avoid

A.A.A. is a valid test of congruency.

S.A.S. works even when the angle is not between the two equal sides.

Any side can be used with two equal angles in A.S.A. or A.A.S. without checking which side it is.
