None normally in a regular 5 sided pentagon but it is possible to construct an irregular pentagon with a pair of parallel sides.
A straight edge or a rule are used to construct straight lines. Laser line setter, In some cases a plumb line
you can coordinate parallel because parallel lines never touch or cross
A straight-edge
Corresponding angle are used to prove if lines are parallel. If they are congruent then the lines cut by the transferal are parallel.
ruler
The simplest way is to construct a square which has two pairs of equal opposite parallel lines
A straight edge or a ruler are used to construct straight lines.
You can construct any polygon with more than 4 sides such that two sides are parallel. A quadrilateral in which two lines are parallel is called a trapezoid.
None normally in a regular 5 sided pentagon but it is possible to construct an irregular pentagon with a pair of parallel sides.
parallel lines are used in the white house. The columns holding it up are parallel lines and the floor and the roof of a room are parallel planes as long as they are the same shape
The instrument that is used to construct straight lines is called a rule. Often people make the mistake of calling it a ruler, but its a rule.
A straight edge or a rule are used to construct straight lines. Laser line setter, In some cases a plumb line
You cannot. You cannot ensure the lines are strictly parallel using only a ruler.
This is Euclid's fifth postulate, also known as the Parallel Postulate. It is quite possible to construct consistent systems of geometry where this postulate is negated - either many parallel lines or none.

Lines parallel to the equator.
