Question

find all the angles of the parallelogram ABCD if angle ABC is 60.​

Answer 1

Answer:

angle ADC =60and other angles r of 120 because opposite angle r equal and the sum of cb =180 so we minus angle c from b then it will be 120

Answer 2

Answer:

given,

ABCD IS A //gm

ABC=60°

we know that in a //gm opposite angels are equal

so,

angle ABC= angle ADC

60°=60° (given)

again,

ABC+DAB=180°

60°+DAB=180°

DAB=120°

DAB=BCD

120°=120°

HENCE ABC=ADC=60°

DAB=BCD=120°
