Warm-Up: Review What You Know

These problems review geometric vocabulary from earlier lessons.

The perpendicular bisector of segment $PP'$ is a line $\ell$ that satisfies two conditions. Which pair correctly states both?

$\ell$ passes through $P$ , and $\ell$ is parallel to $PP'$ .

$\ell$ is perpendicular to $PP'$ , and $\ell$ passes through the midpoint of $PP'$ .

$\ell$ bisects $PP'$ at any angle, and $\ell$ passes through one endpoint.

$\ell$ is perpendicular to $PP'$ , and $\ell$ passes through $P$ .
