equilateral triangle
Any polygonal shape, other than a triangle can have perpendicular lines.
Shape of a T
a rhombus
A plus sign.
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.)
Any polygonal shape, other than a triangle can have 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 rhombus has parallel lines but no perpendicular lines.
Shape of a T
a rhombus
A circle
A perpendicular side is a right angle.A right angle is a perfectly L on any corner.The shape has to have no straight lines that meet.An example would be a triangle.
Lines that form a 90 degree angle at their vertex. Two lines that make a 90 degree are perpendicular.
a square i think
squares or rectangles
