**Transcription and Explanation for Educational Website**

**Given Information:**
- Lines \( L1 \) are parallel to \( L2 \) (written as \( L1 \parallel L2 \)).
- Measure of angle 2 (\( m\angle 2 \)) is \( 132^\circ \).

**Diagram Description:**
The diagram shows two parallel lines, \( L1 \) and \( L2 \), intersected by a transversal \( T1 \). This creates a series of angles at the intersections. The angles are labeled from 1 to 8.

**Task:**
Determine the measure of all other angles and provide reasons for each.

**Table for Angle Measurements and Reasons:**

| Angle | Measure | Reason                               |
|-------|---------|--------------------------------------|
| \( \angle 1 \) | \( 48^\circ \)  | Supplementary (with \(\angle 2\))          |
| \( \angle 2 \) | \( 132^\circ \) | Given                                |
| \( \angle 3 \) | \( 48^\circ \)  | Corresponding (with \(\angle 1\))        |
| \( \angle 4 \) | \( 132^\circ \) | Vertical (equal to \(\angle 2\))        |
| \( \angle 5 \) | \( 48^\circ \)  | Corresponding (with \(\angle 3\))        |
| \( \angle 6 \) | \( 132^\circ \) | Alternate Interior (with \(\angle 2\))  |
| \( \angle 7 \) | \( 48^\circ \)  | Vertical (equal to \(\angle 5\))        |
| \( \angle 8 \) | \( 132^\circ \) | Supplementary (with \(\angle 5\))        |

**Explanation:**
- **Supplementary Angles:** Two angles that add up to \( 180^\circ \).
- **Vertical Angles:** Angles opposite each other when two lines cross; they are always equal.
- **Corresponding Angles:** Angles that are in the same position at each intersection where a transversal crosses parallel lines; they are equal.
- **Alternate Interior Angles:** Angles that are on opposite sides of the transversal and inside the two lines; when the lines are parallel, these angles are
