then <ABC= 180-80=100° (linear pair)
<ADC =100°[opp. angles of a parallelogram are equal)
<DAC=80°(corresponding angles)
<DCB=80°[opp. angles of a parallelogram are equal)
<ADC =100°[opp. angles of a parallelogram are equal)
<DAC=80°(corresponding angles)
<DCB=80°[opp. angles of a parallelogram are equal)
