Question

In the given figure, the arms of two angles are parallel to one another. If $\angle ABC={70}^{\circ }$, then find $\angle DGC$

.

• A. ${110}^{\circ }$
• B. ${70}^{\circ }$
• C. ${90}^{\circ }$
• D. ${35}^{\circ }$

Answer 1

The correct option is B ${70}^{\circ }$

AB ∥ DG
BC is the transversal line intersecting AB and DG
By the property of corresponding angles, $\angle DGC=\angle ABC$
Then, $\angle DGC={70}^{\circ }$
