Question

which angles are adjacent to each other?$angle 1$ and $angle 3LXB0angle 5$ and $angle 2$$angle 1$ and $angle 2$

Explanation:

Adjacent angles share a common vertex and a common side, without overlapping.

1. $\angle1$ and $\angle3$: No common side, not adjacent.
2. $\angle4$ and $\angle2$: No common side, not adjacent.
3. $\angle5$ and $\angle2$: No common side, not adjacent.
4. $\angle1$ and $\angle2$: Share a common vertex and common side, no overlap, so they are adjacent.

Answer:

$\boldsymbol{\angle1 \text{ and } \angle2}$
