Question

1.ABCD is a parallelogram in which angle A=110. Find the measure of each of the angle B,C, and D

Answer 1

Answer:

B=70°, C=110°, D=70°

Step-by-step explanation:

ABCD is a parallelogram

opposite angles are congruent

and adjacent angles are supplementary

angleA=angleC(opposite angles are congruent

therefore angleC= 110°

angleA+angleB=180 (adjacent angles are supplementary)

therefore A+B=180

110+B=180

B=180-110

B=70°

angleB=angleD(opposite angles are congruent)

therefore angleD=70
