Answer:
15) ∠FED, ∠DEF, ∠E, ∠2
16) ∠BCD, ∠DCB, ∠C, ∠3
Step-by-step explanation:
An angle can be named by ...
- naming the rays that form it, in either order
- naming the vertex
- naming the angle designator (often located inside the angle)
15)
The vertex of the angle is point E. It is designated with a 2 inside. The rays that make it up are ray EF and ray ED.
The four names for this angle are ...
∠FED, ∠DEF, ∠E, ∠2
16)
The vertex of the angle is point C. It is designated with a 3 inside. The rays that make it up are ray CB and ray CD.
The four names for this angle are ...
∠BCD, ∠DCB, ∠C, ∠3
