If a straight line cuts two other straight lines so that two alternate angles are equal than the two straight lines are ________
Parallel
Perpendicular
Equal
An current
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
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
If a + b = 180o then a and b are
Supplementary angles
Straight angle
Right angle
Linear pare

180
360
0
