Question

Q.5.Identify two pairs of vertically opposite angles and find the value of angle f.

Answer 1

Answer:

Angles ∠1 and ∠3 form a pair of vertically opposite angles; while angles ∠2 and ∠4 form another pair of vertically opposite angles. Clearly, angles ∠1 and ∠2 form a linear pair. again similarly, ∠2 and ∠3 form a linear pair. Thus, if two lines intersect then vertically opposite angles are always equal.
