In Fig. 5.32, if PQ||RS and QR||TS, then the value a is
(a) 95o (b) 90o (c) 85o (d) 75o
Solution:-
(a) 95o
We know that, corresponding angles are equal
So,
∠ RQP = ∠ TSR = 850 (Corresponding angles)
a + ∠ TSR = 1800
∠a = 95
In questions 42 to 56, fill in the blanks to make the statements true.
If sum of measures of two angles is 90o, then the angles are _________.
Solution:-
If sum of measures of two angles is 90o, then the angles are complementary.
If the sum of measures of two angles is 180o, then they are _________.
Solution:-
If the sum of measures of two angles is 180o, then they are supplementary.
A transversal intersects two or more than two lines at _________ points.
Solution:-
A transversal intersects two or more than two lines at distinct points.
If a transversal intersects two parallel lines, then (Q. 45 to 48).
The sum of interior angles on the same side of a transversal is
Solution:-
The sum of interior angles on the same side of a transversal is 180o.
Alternate interior angles have one common.
Solution:-
Alternate interior angles have one common arm.
Corresponding angles are on the side of the transversal.
Solution:-
Corresponding angles are on the same side of the transversal.
Alternate interior angles are on the side of the transversal.
Solution:-
Alternate interior angles are on the opposite side of the transversal
