answer:
(a) ∠SQR, ∠2
(b) Q
(c) TQ, QR
Step-by-step explanation:
(a) There are many ways in which we can rename angles, but most of the time, they must share a common "center letter" for them to be the same angle. Sometimes, changing the order of first and third letters of the angles works as a way of renaming angles.
(b) The vertex of an angle will always be the letter located "second" of it. For example, if we have ∠ABC, then the vertex will be B.
(c) The sides of an angle are the two lines that form an angle. When you write a side, you will write two letters that identify the line.
