1. All of the angles are adjacent to the two angles on either side of them.

2. $m \angle s = {63}^{\circ}$

3. There are 4 pairs of corresponding angles.

#### Explanation:

Part 1

All of the angles that are right next to each other are adjacent. If two angles share a side, and they have the same vertex, they are considered adjacent. Since all six of the angles formed in Part A share the same vertex, each angle can be considered "adjacent" to the two angles on either side of it.

Part 2

There are three angles along this straight line

Since the angles are on a straight line, they must all add up to ${180}^{\circ}$.

We know that one of the angles is a right angle (${90}^{\circ}$) and another one is ${27}^{\circ}$. Therefore, the last angle must be:

${90}^{\circ} + {27}^{\circ} + m \angle s = {180}^{\circ}$

$m \angle s = {180}^{\circ} - {90}^{\circ} - {27}^{\circ}$

$m \angle s = {63}^{\circ}$

Part 3

When a line intersects another line, four different angles are made (since the two lines form an "X" shape). So, when a transversal intersects TWO lines, there are actually EIGHT angles made: Therefore, since there are two sets of four angles, we say that there are four pairs of corresponding angles. Here they are, labelled individually: Hope this helps!
