Chapter 3: Parallel Lines and Planes

What is the $x$-coordinate of the point$P$?

If $m\angle 1=130$what are the measures of the other numbered angels?

Name the two lines and the transversal that form each pair of angles.

and

If $\overline{ED}||\overline{AC}$, name all pairs of angles that must be congruent.

Complete. $m\angle 9+m\angle 10+m\angle 11=?$

In each exercise some information is given. Use this information to name the segments that must be parallel. If there are no such segments, say so.

$m\angle APL+m\angle PAR=180$

Find the value of x

In each exercise some information is given. Use this information to name the segments that must be parallel. If there are no such segments, write none.

$\overline{FC}\perp \overline{AE}$and $\overline{FC}\perp \overline{AE}$

Four of the angles of a pentagon have measures 40, 80, 115, and 165. Find the measure of the fifth angle.

Find the values of $x$and $y$
