Answer:

#4

PS║RT - given

  • PQ ≅ TQ - given
  • ∠PQS ≅ ∠TQS - vertical angles
  • ∠SPQ ≅ ∠RTQ - alternate interior angles

ΔPSQ ≅ ΔTRQ - ASA Postulate

#5

BD bisects ∠ADC - given

BD⊥AC - given

  • ∠ADB = 1/2∠ADC and ∠CDB = 1/2∠ADC    ⇒ ∠ADB ≅ ∠CDB
  • ∠DBA = 90°, ∠DBC = 90°                             ⇒ ∠DBA ≅ ∠DBC
  • DB ≅ DB - reflexive property

ΔABD ≅ ΔCBD - ASA Postulate
