The figure,given below,show a pair of parallel lines cut by a transversal.Find 'a' and 'b' ?
a = 75o b = 75o
a = 70o b = 70o
a = 60o b = 100o
a = 70o b = 65o
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
From ΔPQR calculate ∠QPR
80
65o
60o
90
Distance between the two parallel line is __________
Same
Different
Zero
Not defined
90o angle is called _______
Right angle
Straight angle
0
Calculate ∠a, ∠b and ∠c
50, 60, 70
40, 90, 100
50, 360, 90
40, 140, 40
a = 110o b = 70o
a = 60o b = 30o
a = 60o b = 65o
