Which angle is the included angle for de¯¯¯¯¯ and fe¯¯¯¯¯ ? ∠d ∠e ∠f

∠E

Step-by-step explanation:

The  included angle for and    is .

The included angle for any two lines or line segments is represented by the common vertex point.

For example : The included angle for and is [Since B is the common end point in and   ]

Similarly, the  included angle for and    is  (Since E is the common vertex in   and   )

what’s the question?

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
