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 = 75o b = 75o
a = 135o b = 75o
Distance between the two parallel line is __________
Same
Different
Zero
Not defined
If a + b = 180o then a and b are
Supplementary angles
Straight angle
Right angle
Linear pare
The figure,given below,show a pair of parallel lines cut by a transversal.Find 'a' and 'b' ?
a = 70o b = 70o
a = 60o b = 100o
a = 70o b = 65o
