Any polygonal shape, other than a triangle can have perpendicular lines.
Shape of a T
a rhombus
A plus sign.
equilateral triangle
Perpendicular lines are lines that eventually intersect, and intersecting means when the run into eachother. For example, the "L" shape are two perpendicular lines because the lines run into eachother.
A rhombus has parallel lines but no perpendicular lines.
Shape of a T
a rhombus
A circle
Lines that form a 90 degree angle at their vertex. Two lines that make a 90 degree are perpendicular.
a square i think
A plus sign.
a square or a rectangle
squares or rectangles
equilateral triangle
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.
