Question

While constructing a parallel line to a given line, we______.

• A. copy a segment
• B. bisect a segment
• C. copy an angle
• D. construct a perpendicular

Answer 1

The correct option is C copy an angle

To draw a parallel line to a given line $l$, we have to just copy the angle $\angle AOL$, so that

$\angle AOL=\angle AEM$

In this case $AB$ act as a transverse and $\angle AOL$ and $\angle AEM$ are corresponding angles and they are equal if line $l$ is parallel to line $m$
