Given :- If two lines intersect each other and one angle of vertically opposite angles pair is 125° then what will be measurement of another angle ?
Solution :-
from image , we have ,
- Line AB and CD intersect at O .
- ∠AOC = ∠BOD = 125° (given)
since , AB is a straight line .
so,
→ ∠AOC + ∠BOC = 180° (Linear pair angles.)
then,
→ 125° + ∠BOC = 180°
→ ∠BOC = 180° - 125°
→ ∠BOC = 55° .
therefore,
→ ∠BOC = ∠AOD (vertically opposite angles.)
→ ∠AOD = 55° .
Hence, the measurement of another pair of vertically opposite angles is 55° .
