in the given figure,AB||CD and EF⊥AB.if EG is a transversal, such that ∠GED=130∘,find ∠EGF.
ANSWER:
In the given figure, AB || CD and GE is the transversal.
∴ ∠GED+∠EGF=180∘
supplementary)
(Sum of adjacent interior angles on the same side of the transversal is
⇒ 130∘+∠EGF=180∘
⇒ ∠EGF=180∘−130∘=50∘
Thus, the measure of ∠EGFis50∘.
