Question

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

Explanation:

Step1: Recall angle - naming rules

An angle can be named by the vertex alone (if there is only one angle at that vertex), by three points with the vertex in the middle, or by a number.

Step2: Answer part (a)

For $\angle EFH$, two other names are $\angle HFE$ and $\angle 2$.

Step3: Answer part (b)

The vertex of $\angle HFG$ is point $F$.

Step4: Answer part (c)

The sides of $\angle 1$ are $\overrightarrow{FG}$ and $\overrightarrow{FE}$.

Answer:

(a) $\angle HFE$, $\angle 2$
(b) $F$
(c) $\overrightarrow{FG}$, $\overrightarrow{FE}$
