No. Lines can intersect at any possible angle.
Skew lines never intersect. If two lines intersect, then they are known as "intersecting lines", not skew lines.
always. if two lines intersect, then exactly one plane contains the lines.
sometimes
The intersection of two planes is never a point. It's usually a line. But if the planes have identical characteristics, then their intersection is a plane. And if the planes are parallel, then there's no intersection.
No, intersecting lines can intersect at any angle.
No. Lines can intersect at any possible angle.
No. If the lines are parallel they will never meet or intersect at any point. If the lines are perpendicular they do intersect, but perpendicular lines are a special case of intersecting lines. Perpendicular lines are exactly 90 degrees from each other. Intersecting lines do not haveto be perpendicular... but perpendicular lines are always intersecting.

Sometimes.Perpendicular lines always intersect.Parallel lines never intersect.Therefore, intersecting lines may be perpendicular, but not always.
Parallel lines cannot intersect in the Euclidean plane. Intersecting lines are not parallel.
Form right angles
The intersection of two planes is never a point. It's usually a line. But if the planes have identical characteristics, then their intersection is a plane. And if the planes are parallel, then there's no intersection.
