If a transversal intersects a pair of line making alternate interior angles, then the lines are
Parallel
Perpendicular
Intersecting
None of these
In a theorem ‘ then ‘ part is called
Existential part
Uniqueness
Both (1) and (2)
A line which intersects a pair of lines at two distinct points is called
Transversal
In the below figure angle corresponding to ∠C is
∠F
∠E
∠A
∠G
In a theorem ‘ if ‘ part is called
. If ∠A : ∠B = 2 : 3 then ∠A =
180o
72o
45o
30o
Number of points that can be plotted on a line is
2
4
3
Infinite
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
l, m are two lines such that l U m = Φ then 1, m are
Concurrent
Intersecting lines
If a pair of parallel lines, intersected by a transversal then the sum of interior angles on the same side of transversal is
90o
360o
270o
