Answer:
interior
Explanation:
An angle is formed by two rays that have a common endpoint.
In this problem, angle WXY is formed by the rays XW and XY.
The common endpoint of the rays is X.
The area between the rays is the interior of the angle.
The area outside the rays is the exterior of the angle.
The points on the rays are on the actual angle, so they are neither interior nor exterior points.
Point Z is between rays XW and XY, so point Z in in the interior of the angle.
