Answer:
Angle E is the included angle between the sides FE and DE
The included angle between sides FE and DF is the angle F
Step-by-step explanation:
we know that
An included angle is the angle between two sides of a triangle
In the triangle DEF
we have
The included angle F is the angle between the sides FE and FD
The included angle E is the angle between the sides FE and DE
The included angle D is the angle between the sides DF and DE
therefore
In this problem
Angle E is the included angle between the sides FE and DE
The included angle between sides FE and DF is the angle F
