Question

name two adjacent angles. __ and __

Explanation:

Step1: Recall adjacent angles definition

Adjacent angles share a common side and vertex, and their non - common sides are adjacent rays.

Step2: Identify adjacent angles from the diagram

Looking at the diagram, $\angle1$ and $\angle2$ share a common vertex and a common side, and their non - common sides are adjacent. Also, $\angle2$ and $\angle3$ (since $\angle3$ is a right angle, marked as $90^{\circ}$) share a common vertex and side. Another pair could be $\angle7$ and $\angle8$, they share a common vertex and side (the intersecting lines create them with a common side and vertex). Let's take $\angle1$ and $\angle2$ as an example.

Answer:

$\angle1$ and $\angle2$ (Other valid pairs like $\angle2$ and $\angle3$, $\angle7$ and $\angle8$ etc. are also correct)
