Question

select the correct answers. if an angle is represented with three numbers: 9,8, and 7 and 9 is the origin of the two rays. which of the followings are be the angles names.
a ∠9
b ∠9,8,7
c ∠8,9,7
d ∠7,9,8
e ∠7,8,9

Explanation:

When naming an angle with three - point notation, the vertex (origin of the two rays) is the middle number. Given that 9 is the origin (vertex) of the two rays, in the three - point notation of an angle, the vertex is in the middle.
For option C (\(\angle8,9,7\)), the vertex is 9.
For option D (\(\angle7,9,8\)), the vertex is 9.

Answer:

C. \(\angle8,9,7\), D. \(\angle7,9,8\)
