Two straight lines that remain equal distance apart are parallel lines.
Polygon: A closed shape bounded by straight lines.
definition mixed lines
Horizontal lines:)
Depends. Probably not because nothing is perfect! :)i have to disagree - the sides of crystals are straight~*Sigh*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.
Straight lines.
you draw straight lines with a ruler
there are 5 straight lines
Straight lines that never cross are called parallel lines.
Straight
Despite Straight Lines was created in 1983.
Think about this: A straight angle makes 180 degrees, right? Straight lines, when measured by a compass, are also 180 degrees. So, yes, all straight angles are straight lines.
A straight edge or a ruler are used to construct straight lines.
Not necessarily. The horizontal and diagonal lines are also straight lines.
Two straight lines that remain equal distance apart are parallel lines.
No. A circle has no straight lines. You can approximate circles with very small straight lines (that's how a computer draws circles) but mathematically, no.
