Question

use the figure to complete each part.
(a) name the sides of ∠2.
and
(b) write two other names for ∠1.
and
(c) name the vertex of ∠sqr.

Explanation:

Part (a)

Step1: Recall angle side definition

An angle's sides are the two rays forming it. For $\angle 2$, the vertex is $Q$, and the rays are $QR$ and $QS$.

Step1: Recall angle naming rules

An angle can be named by vertex (if unique) or by three points (vertex in middle). For $\angle 1$, vertex is $Q$, rays are $QT$ and $QR$. So names are $\angle TQR$ and $\angle RQT$.

Step1: Recall vertex definition

The vertex of an angle is the common endpoint of its two sides. For $\angle SQR$, the sides are $\overrightarrow{SQ}$ and $\overrightarrow{RQ}$, common endpoint is $Q$.

Answer:

$\overrightarrow{QR}$ and $\overrightarrow{QS}$

Part (b)
