The figure,given below,show a pair of parallel lines cut by a transversal.Find 'a' and 'b' ?
a = 110o b = 70o
a = 75o b = 75o
a = 60o b = 30o
a = 60o b = 65o
A straight angle is an angle which is equal to _________

If ∠POQ = 65o, ∠ROS = 70o, ∠QOR = 110o calculate ∠SOP
135
150o
115o
The figure,given below,show a pair of parallel lines cut by a transversal.Find 'a' and 'b'?
a = 75o b = 60o
a = 60o b = 120o
a = 135o b = 75o
