Answer 1

Did you understand the previous plane question on naming it?

Answer 2

Yes!

Answer 3

It was SLT right?

Answer 4

SLT is a plane that is diagonal to the "flat" plane, Z.

The previous question wanted you to find 3 points that sit on the flat plane... look at X, T, and V... they are all sitting on the "table" that is plane Z.

Point S is NOT on that plane... it is up in the air above plane Z

Answer 5

Oh, I think I get it now, thank you so much!

Answer 6

This one says, look at the diagonal plane that runs through S, L, and T.... (it's like a piece of paper held at an angle to your desk)

Where does it intersect plane Z, the desk?

Hint, planes intersect other planes in a line, like the edge of the paper with the desk.

Answer 7

Would it be STV?

Answer 8

Elizabeth, sorry, I stepped away. The intersection line between those 2 planes must sit on both planes. STV is a different plane that also is like paper standing vertically on a table Z.

SLT is diagonal "paper" leaning to the left, and intersecting the "table" plane Z along the little ray "TL" that starts in the middle of the plane Z and goes away from you.
