triangle congruence: sas
identifying included angles
use △def to complete the statements.
angle e is the included angle between sides.
the included angle between sides fe and df is angle.

Explanation:

Step1: Recall the definition of included angle

An included angle is the angle between two sides of a triangle.

Step2: Determine the sides for angle E

For angle \( E \) in \( \triangle DEF \), the two sides that form the angle are \( FE \) and \( DE \).

Step3: Determine the included angle for sides \( FE \) and \( DF \)

The angle between \( FE \) and \( DF \) is angle \( F \) as it is the vertex where these two sides meet.

Answer:

1. \( FE \) and \( DE \)
2. \( F \)
