Sample problems

Show your work in the space provided. When two parallel lines are cut by a transversal: corresponding, alternate interior, and alternate exterior angles are equal, while co-interior (same-side interior) angles are supplementary, adding to $18 0^{\circ}$ . Vertical angles are also equal, and a linear pair sums to $18 0^{\circ}$ .

1. Two parallel lines are cut by a transversal. A pair of alternate exterior angles is formed, and one measures $12 6^{\circ}$ . Find the measure of the other.
2. Two parallel lines are cut by a transversal. A pair of co-interior (same-side interior) angles is formed, and one measures $8 2^{\circ}$ . Find the measure of the other.
3. Two parallel lines are cut by a transversal. One angle measures $4 7^{\circ}$ . Find the measure of its corresponding angle and the measure of the angle that forms a linear pair with it.
4. Lines $m$ and $n$ are parallel. The two marked angles are corresponding angles. Find the value of $x$ .
