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.
I think it is either a right triangle, square, pentagon, or rectangle.
A regular 5 sided pentagon has no perpendicular lines
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 pentagon does not. An irregular pentagon can.
No, a pentagon is not perpendicular. The word perpendicular describes two lines (or line segments) that meet at a 90o angle.
a pair of intersecting lines that are perpendicular
Lines that intersect at 90 degrees are perpendicular lines
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.
No parallel lines but a right angle triangle has perpendicular lines.
A plus sign (+) would be a pair of perpendicular line segments.
The lines that meet at right angles are perpendicular to each other.
A perpendicular diagonal is a pair of segments or lines that cross a polygon making a perpendicular
One pair of perpendicular lines would create one right angle. Some kites have one right angle.
A regular pentagon has no parallel lines, but you can create an irregular pentagon with one pair of parallel lines if you make a traditional 'house' shape with parallel 'walls'.
Any two perpendicular lines ... meaning any pair of them ... are coplanar.
No because perpendicular goes up and down
Negative reciprocal slopes always represent perpendicular lines.
Two lines that are perpendicular to the same plane are coplanar. This means that they lay on the same plane.
A right angle triangle has a pair of perpendicular lines that meet each other at 90 degrees.
A rectangle or a square
