Name the vertex and sides of each angle

 7) vertex = ∠H       sides = HG and HI

                8) ∠H, ∠IHG, ∠GHI, ∠4

                9) ∠HVI, ∠HVJ, ∠IJV

NOTES:

1) The vertex is the point where the two segments, rays, or lines connect.

2) When naming an angle, the vertex is ALWAYS written in the middle with the sides on the left and right.

you just switch the numbers basically so it would be 3/17

-1   1/6.   you dont subtract the denominators
