Question

in the adjoining figure if AB ||CD and angle 1=80° find the other angles​

Answer 1

Answer:

if angle 1=80 then angle 3=80 due to corresponding angles

angle 3 is 80 then angle 5 is 80 due to co-interior angles

angle 5 is 80 then angle 7 is 80 due to corresponding angles

therefore,angle 1+2=180degree so

--- 80+x=180

--- x=100

now angle 2 and 4 is equal to 100 degree due to corresponding angles

angle 4& 6=100 due to co-interiorangles

angle 6and8=100 due to corresponding angles
