Question

sketch plane m intersecting plane n. then sketch plane o so that it intersects plane n , but not plane m

Answer 1

You can think of m and n as planes view from the top. Now can you draw o like this?

Answer 2

Sketch a plane "O" so that it is parallel to "M". It won't intersect M because it is parallel to it.

Answer 3

Indeed, o has to be parallel with m, because that's the only way two lines (and two planes) can not intersect each other
