Question

In the given figure, $\angle 3$=$\angle 8$. Then-

• A. Line $AB$ is parallel to line $CD$
• B. Line $AB$ is not parallel to line $CD$
• C. $\angle 3$ and $\angle 8$ are corresponding angles
• D. $\angle 3$ and $\angle 8$ are alternate interior angles

Answer 1

Answer: (A), (C)

The correct options are
A Line $AB$ is parallel to line $CD$
C $\angle 3$ and $\angle 8$ are corresponding angles

$\angle 3$ and $\angle 8$ are corresponding angles. We know that, when the corresponding angles are equal, the lines are parallel. As $\angle 3$=$\angle 8$, i.e., the corresponding angles are equal
$\Rightarrow$ line $AB$ is parallel to line $CD$.
