In figure pairs of interior angles on the same side of the transversal are
∠A, ∠H ; ∠B, ∠G
∠B, ∠H ; ∠A, ∠G
∠C, ∠F ; ∠D, ∠E
∠C, ∠E ; ∠D, ∠F
If a pair of parallel lines, intersected by a transversal then the sum of interior angles on the same side of transversal is
180o
90o
360o
270o
In the figure p||q and r||s then ∠A + ∠C =
Can’t be determined
Number of points that can be plotted on a line is
2
4
3
Infinite
l, m are coplanar lines and l ∩ m = { p } then the lines
Parallel
Perpendicular
Intersecting at p
Non – intersecting
In a theorem ‘ then ‘ part is called
Existential part
Uniqueness
Both (1) and (2)
None of these
if l || m and ∠A = 70o then ∠F =
70o
35o
140o
110o
In the below figure one pair of alternate interior angle is ∠C and ∠E then the other pair is
∠C , ∠D
∠B, ∠F
∠D, ∠F
∠G, ∠H
If a transversal intersects a pair of line making alternate interior angles, then the lines are
Intersecting
In a theorem ‘ if ‘ part is called
