Explanation:

Step1: Identify line - segments in first figure

Line - segments are parts of a line with two endpoints. In the first figure, they are $\overline{PQ},\overline{QR},\overline{QS},\overline{ST},\overline{QU},\overline{QV}$.

Step2: Identify rays in first figure

Rays are parts of a line with one endpoint and extend infinitely in one direction. In the first figure, they are $\overrightarrow{QU},\overrightarrow{QV},\overrightarrow{QS},\overrightarrow{ST},\overrightarrow{PQ},\overrightarrow{QR}$.

Step3: Identify points in first figure

Points are the locations in the figure. In the first figure, they are $P,Q,R,S,T,U,V$.

Step4: Identify line - segments in second figure

In the second figure, line - segments are $\overline{PL},\overline{LK},\overline{LM},\overline{PQ},\overline{QL},\overline{QR}$.

Step5: Drawing for part C

Draw a straight line, mark two points $A$ and $B$ on it to form line - segment $\overline{AB}$. Mark a point $C$ on the line and consider the part starting from $C$ and extending infinitely in one direction as ray $\overrightarrow{CA}$.

Answer:

A.
line segments: $\overline{PQ},\overline{QR},\overline{QS},\overline{ST},\overline{QU},\overline{QV}$
rays: $\overrightarrow{QU},\overrightarrow{QV},\overrightarrow{QS},\overrightarrow{ST},\overrightarrow{PQ},\overrightarrow{QR}$
points: $P,Q,R,S,T,U,V$
B. $\overline{PL},\overline{LK},\overline{LM},\overline{PQ},\overline{QL},\overline{QR}$
C. Draw a straight line. Mark two points $A$ and $B$ to form line - segment $\overline{AB}$. Mark a point $C$ on the line and form ray $\overrightarrow{CA}$ (drawing should be done on paper).
