Question

measure of one of the angle of parallelogram is 70 degre . find the measure of the remining angle

Answer 1

Answer:

adjacent angle 110*(degree) opp angle 70degree and angle opp to adjacent angle 110*

Answer 2

Answer:

opposite angles of parallelogram are equal

let ABCD be a parallelogram

angleA+angleB+angleC+angleD=360 ....angle sum property of parallelogram

angleA=angleC=70

and,

angleB=angleD

so,

70+angleB+70+angleD=360

angleB+angleD=360-140

2(angleB)=220

angleB=110
