What is the word for when a plane is not necessarily perpendicular to another plane but at an angle to it?

So I know that when two planes intersect each other at 90 degree angles, they are described as orthogonal. But what is the word for when two planes intersect each other at an angle less than 90 degrees?

Isn't that just normal intersection? I mean intersection of any 2 planes that is not at 90° will always have 2 <90° (acute) angle and 2 >90° (obtuse) angle

In general you might describe two non-parallel planes as *oblique* but this would include the special case of orthogonal planes.
You might hear non-orthogonal planes loosely described as oblique but it's not capturing precisely what you mean. (Just as someone might use *rectangle* in a situation where they really mean a *non-square rectangle*.)
