Question

For the diagram above, if $CD$ and $PQ$ are parallel to each other, then $\angle 3=$.

• A. $\angle 4$
• B. $\angle 5$
• C. $\angle 8$

Answer 1

The correct option is B $\angle 5$

For the diagram given:
$angle3$ and $\angle 5$ are alternate interior angles.
Also, $CD$ and $PQ$ are parallel to each other.
$\therefore$ Using alternate interior angles theorem
$\angle 3=\angle 5$
