Answer:
Points X and Y lie on more than one plane.
Step-by-step explanation:
From the figure attached we have to find the points which lie on more than one plane.
M and R :
These are the points which lie on only one plane painted in yellow color.
A and S
These points lie on a plane perpendicular to the plane painted in yellow color.
X and Y :
These points lie on both the planes, painted in yellow color and the plane perpendicular to this.
M and S :
Point M lies on a plane in yellow color and point S lies on a plane perpendicular to the yellow plane.
Therefore, points X and Y lie on more than one plane.
