Q. 23

Statements a and A. Both a and b are true

B. a is true and b is false

C. a is false and b is true

D. both a and b are false

Answer :

When two lines intersect then the vertically opposite angles are always equal.


When a transversal intersects, two other lines, then the sum of two interior angles on the same side of the transversal is 180° if and only if the two lines are parallel. The pair of angles are known as co-interior angles.


So both a is true and b is false.
