Clocked In Punched Out

given:
segment AD bisects segment BC
segment BC bisects segment AD

prove:
ΔABM and ΔDCM are congruent

1. segment AD bisects segment BC 1. given
2. segment AM ≅ segment DM 2. when a segment is bisected, the two resulting segments are congruent
3. segment BC bisects segment AD 3. given
4. segment BM ≅ segment CM 4. when a segment is bisected, the two resulting segments are congruent
5. ∠AMB ≅ ∠CMD 5. vertical angles are congruent
6. ΔABM ≅ ΔDCM 6. SAS postulate (2, 4, 5)

Still got it.
