STEP 1

What is this asking? We need to identify different names for an angle, the point where the angle's lines meet, and the lines that form a specific angle, using the given diagram. Watch out! Be careful to use the correct order of letters when naming angles – the middle letter should always be the vertex!

STEP 2

1. Find other names for the angle.
2. Identify the vertex.
3. Name the sides of the angle.

STEP 3

We're looking for other names for QMP\angle QMP.
Remember, the middle letter represents the **vertex** of the angle, which is the point where the two sides of the angle meet.
The other two letters represent points on each of the two sides.

STEP 4

So, for QMP\angle QMP, the vertex is MM.
We can switch the order of the other two letters, QQ and PP, and the angle will still be the same.

STEP 5

Therefore, another name for QMP\angle QMP is PMQ\angle PMQ.
Also, we see that QMP\angle QMP is labeled as 2\angle 2 in the diagram.
So, 2\angle 2 is another name for QMP\angle QMP.

STEP 6

We need to find the vertex of PMN\angle PMN.
The **vertex** is the point where the two sides of the angle meet.

STEP 7

In PMN\angle PMN, the middle letter, MM, represents the vertex.

STEP 8

We're asked to name the sides of 1\angle 1.
Looking at the diagram, 1\angle 1 is formed by two line segments that extend from point MM.

STEP 9

One side goes from MM to PP, which we can write as MP\overline{MP} or PM\overline{PM}.
The other side goes from MM to QQ, which we can write as MQ\overline{MQ} or QM\overline{QM}.

STEP 10

So, the sides of 1\angle 1 are MP\overline{MP} and MQ\overline{MQ}.

STEP 11

(a) Two other names for QMP\angle QMP are PMQ\angle PMQ and 2\angle 2. (b) The vertex of PMN\angle PMN is MM. (c) The sides of 1\angle 1 are MP\overline{MP} and MQ\overline{MQ}.
