Question

Which angle is the included angle for DE¯¯¯¯¯ and FE¯¯¯¯¯ ?

∠D

∠E

∠F

Answer 1

The correct answer is: ∠E

Answer 2

Answer: ∠E

Explanation:

The included angle for
`\overline{DE}` and
`\overline{FE}` is
`\angle{E}`.

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

For example : The included angle for
`\overline{AB}` and
`\overline{BC}` is
`\angle{B}` [Since B is the common end point in
`\overline{AB}` and
`\overline{BC}` ]

Similarly, the included angle for
`\overline{DE}` and
`\overline{FE}` is
`\angle{E}` (Since E is the common vertex in
`\overline{DE}` and
`\overline{FE}` )
