intersecting lines * * * * * Non-perpendicular intersecting lines. Or else the angles would be right angles.
acute, obtuse and right angles
An line that is not perpindicular to the other line makes an acute or obtuse angle Oblique lines are not parallel or perpendicular which would be lines that form acute or obtuse angles at the point of intersection.

NO!!! The word 'perpendicular' means that the lines intersect at 90 degrees (right anhles).
