Depends. Probably not because nothing is perfect! :)
i have to disagree - the sides of crystals are straight

All lines are straight. A man-made one may not be, but by the correct definition, all lines are straight. Straight lines are a mathematical concept - an ideal concept - and therefore, conceptually, all lines are straight even if man-made ones are mere approximations.
Yes. If it is not straight, then it is not a line.
it just a straight line
If it is not straight, then it is not a line.
The word straight does have an antonym, which is crooked. So perhaps a crooked line is the opposite of a straight line.
The length (distance) of a straight line always changes, the angle of a straight line is 180 degrees.

Displacement of a straight line is zero...
A straight line has no vertex.

There are 180 degrees on a straight line.

The straight-line distance is 1,030 miles (to the coastline of Puerto Rico). This is the true straight line distance which accounts for the curvature of the earth, NOT simply a straight line drawn on a map.
A line that goes straight acrosswould be ahorizontal line.
A straight line is a line with the property that, if you pick any two points on the line and connect these points with a straight line, then every point on this new line lies on the original line.
The straight-line distance is 1885.7 miles. This is the true straight line distance which accounts for the curvature of the earth, NOT the straight line drawn on a map.
