which names are other ways to name ∠3?
select each correct answer.
□ ∠tec
□ ∠cet
□ ∠t
□ ∠ect
□ ∠c
□ ∠etc
□ ∠e

Explanation:

An angle can be named by the vertex letter (if there is only one angle at that vertex) or by three - letter combinations where the middle letter is the vertex. Here, the vertex of the angle is \(E\). The correct three - letter names for the angle are those where \(E\) is in the middle. Also, if there is only one angle at the vertex, the vertex letter alone can be a name.

Answer:

∠CET, ∠TEC, ∠E
