Question

11 name each figure using proper notation. a) figure with endpoints r and s b) figure with point a (start) and point b (along a ray with arrow) c) figure with line ab (a at bottom, b at top, arrow down from a), ray bc (from b to c, arrow), and an angle at b

Explanation:

Step1: Analyze Figure a)

Figure a) has two endpoints R and S, so it is a segment. The notation for a segment is $\overline{RS}$.

Step2: Analyze Figure b)

Figure b) has a starting point A and extends infinitely in the direction of B, so it is a ray. The notation for a ray is $\overrightarrow{AB}$.

Step3: Analyze Figure c)

Figure c) shows two rays, $\overrightarrow{BA}$ and $\overrightarrow{BC}$, with a common endpoint B, forming an angle. The notation for an angle is $\angle ABC$ (or $\angle CBA$).

Answer:

a) $\overline{RS}$
b) $\overrightarrow{AB}$
c) $\angle ABC$ (or $\angle CBA$)
