Any polygonal shape, other than a triangle can have perpendicular lines.
equilateral triangle
Perpendicular lines meet at a right angle so a right angled triangle has two lines which are perpendicular to eachother. However there are no parallel lines in a right angled triangle, or any triangles for that matter.
nope, only right/equilateral triangles do.
A regular pentagon does not have parallel or perpendicular lines. Some other possibilities include, but are not limited to:a circlean ovalan equilateral triangle or any triangle that is not a right triangle.(A right angle's lines are perpendicular. Those are what make it a 90 degree angle.)
no a equilateral triangle does not have any perpendicular sides because the lines are joined together.

There are no parallel lines in any triangle but a right angle triangle has perpendicular line that meet each other at 90 degrees.

It is perpendicular to any of its 3 vertices.
a triangle, pentagon and that's all i can think of * * * * * A right angled triangle has a pair of perpendicular lines! Likewise, a pentagon can have a pair. A circle, ellipse etc do not.
Any pair or rays which are not mutually perpendicular.
A polygon need not have ANY perpendicular or parallel lines. For example, consider an equilateral triangle. It can happen that two sides of a polygon, extended if necessary, meet at a point where they form a 90 degree angle. Those two lines are perpendicular. There may be pairs of lines such that, no matter how far you extend them in either direction, they will never meet. Such lines are parallel. A triangle cannot have parallel lines but it can have perpendicular lines. Any polygon of 4 or more sides can have sides that are perpendicular or parallel (or some of each).
Yes, because you can notice that the right angled triangle has one right angle, so its only 1 perpendicular line. Hope this helped :D
