Question

E
D
F
It’s number 14

Answer 1

Answer: Yes
`\angle FDE` is one possible angle name

Another name is
`\angle EDF`

When it comes to naming an angle this way, all we need to worry about is the vertex point. This is where the angle hinges (think of a door or a pair of scissors). In this case, the hinge or vertex point is at point D. The vertex is always the middle letter of any three-letter sequence. The order of the other two points does not matter.

This is why saying "angle FDE" is the same as "angle EDF".
