Answer 1

Maybe not any common points, but do planes PQR and UVS share any common lines or segments?

Answer 2

No they dont.

Answer 3

look at the square that contains PQR not just those 3 points.

Answer 4

same with UVS

Answer 5

I take that back... U and Q are lines right?

Answer 6

*a line

Answer 7

PQR = PQRS
QUV=QUVS

Answer 8

what do they have in common?

Answer 9

S

Answer 10

and?

Answer 11

@pooja195
Keep in mind that just like a line is infinite in both directions, a plane is an infinite flat surface. Plane UVS is being called plane UVS to show you that these three points are in the plane. The plane extends up and down and right and left infinitely.

Answer 12

Q

Answer 13

Every point on the front surface of the prism is part of plane UVS.

Answer 14

The same goes for plane PQR. Every point on the right face of the prism is part of plane PQR.

Answer 15

In addition, when planes do intersect, their intersection is a line.

Answer 16

right they share QS in common
