Answer:
The sides of an angle are the rays of the angle. So,
1)The sides of ∠YVW are the 2 rays of the angle VY and VW
2)The sides of ∠XVY are the 2 rays of the angle VX and VY
Angles adjacent to an angle are the angles next to the main angle
3)The angle adjacent to ∠ZVW is ∠YVZ and ∠WVX
4)The angle adjacent to ∠XVZ is ∠ZVW and ∠XYW
5)The angle adjacent to ∠YVZ is ∠ZVW and ∠YVX
The side common to the angles is the common ray of both angles
6)The side common to ∠XVY and ∠YVZ is ray VY
7)The side common to ∠XVZ and ∠ZVW is ray VZ
8)The side common to ∠XVZ and ∠ZVY is ray VZ
9)The side common to ∠XVY and ∠YVW is ray VY
The common vertex is the point where all rays converg,
10)The common vertex is V
