Question

use the figure to complete each part.
(a) name the vertex of $\angle hfe$.
(b) name the sides of $\angle 2$.
\boxed{} and \boxed{}
(c) write two other names for $\angle 1$.
\boxed{} and \boxed{}

Explanation:

(a) The vertex of an angle is the common endpoint of its two sides. For ∠HFE, the common endpoint is point F.
(b) ∠2 is formed by the two line segments meeting at F, which are FH and FE.
(c) ∠1 can be named by its vertex alone (since no other angles share only this vertex) or by reversing the order of the side labels, so ∠EFG and ∠F are valid alternate names.

Answer:

(a) $F$
(b) $\overline{FH}$ and $\overline{FE}$
(c) $\angle EFG$ and $\angle F$
