Answer by mananth(16946) (Show Source): You can put this solution on YOUR website!
angle 7 is =135 ( vertically opposite angle)
Angle 5 = 45 deg. supplementary to 135
Angle 6 = 45 ( vertically opposite to angle 5)
Angle 7 = angle 1 =135 deg(Alternate angles)
Angle 1 - angle 3= 135 deg (Vertically opposite angles)
Angle 2= 45 deg. (supplementary to angle 1)
Angle 2= angle 4 = 45 deg vertically opposite angles)
