Question

use the figure to complete each part.
(a) name the sides of $angle 1$.
$square$ and $square$
(b) name the vertex of $angle sqt$.
$square$
(c) write two other names for $angle rqs$.
$square$ and $square$

Explanation:

(a) An angle's sides are the two rays forming it. ∠1 is formed by rays from Q to T and Q to R.
(b) The vertex of an angle is the common endpoint of its two sides. ∠SQT has sides QS and QT, meeting at Q.
(c) An angle can be named by its vertex alone (if unique) or by reversing the order of the side labels (keeping the vertex in the middle). ∠RQS can also be called by its number ∠2, or ∠SQR.

Answer:

(a) $\overrightarrow{QT}$ and $\overrightarrow{QR}$
(b) $Q$
(c) $\angle 2$ and $\angle SQR$
