No. Perpendicular lines for right angles. That is why they are called perpendicular.
If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.
perpendicular lines run at 90% angles to each other not Parallel
Perpendicular: No Parallel: Yes, two pairs.
Non-perpendicular intersecting lines. There is no special name.
yes they do. they have a perpendicular line. * * * * * No, a pentagon, as in a regular polygon does not have perpendicular lines. An irregular pentagon could, and you can always add perpendicular lines to any shape.
A regular 5 sided pentagon has no perpendicular lines
A regular pentagon does not. An irregular pentagon can.
An irregular pentagon can. A regular pentagon cannot.
No, a pentagon is not perpendicular. The word perpendicular describes two lines (or line segments) that meet at a 90o angle.

A pentagon can have 0, 1 or 2 pairs of parallel lines. It can have 0 to 4 lines perpendicular to an adjacent line. A rhombus must have two pairs of parallel lines and none of them may be perpendicular to any other.
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.
A circle.
A rectangle or a square
A regular pentagon does not have any perpendicular sides. A pentagon is made up of five sides. An irregular pentagon which has sides that are not equal may have a perpendicular side.
