2

2

Draw opposite rays

<----.B-----.-------.A----->

3

Where do lines PR and TR intersect?

Point R

4

Sketch two lines: one that lies on plane K and a second that intersects the first line on the same plane

5

Draw plane M with 2 lines SQ and PR that intersect at point Q.

Now add point T that is coplanar to the 2 lines.
