Not in Euclidian plane geometry.
Yes it can. Actually in non-euclidian geometry its possible that two parallel lines may form a angle, but it can never be possible in convention euclidian geometry (in which some of angles of a triangle is always 180 degrees, etc., such things are not sure in non-euclidian geometry).

The artist MC Esher used Euclidian geometry in many of his works.
One of the qualitative Euclidian definitions of parallel lines is that they never meet.
An affine combination is a linear combination of vectors in Euclidian space in which the coefficients add up to one.
No. It's first in first out.
It is inventory. First in first out.
First it's what is the definition OF not TO.Have you tried typing Define: Principle in google?
Yes. The geometry taught in today's public schools is based on Euclidian geometry.
