Answer 2

Answer:

Angle BAD = 80°

Angle ABC = 100°

Angle BCD = 80°

Angle ADC = 100°

Step-by-step explanation:

Ang. ABC + 80° = 180° [Linear pair]

=> ABC = 100°

Ang. ADC = Ang. ABC = 100° [Opposite angles are equal in a parallelogram]

DC is || to AB and AD is a transversal

Ang. ADC + Ang. BAD = 180° [Co-interior angles]

=> 100° + BAD = 180°

=> BAD = 80°

Ang. BCD = Ang. BAD = 80° [Opposite angles are equal in a parallelogram]
