Which points lie on more than one plane? m and r a and s x and y m and s

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.
