A circles has no perpendicular lines. Perpendicular lines are two straight lines that join forming 90 degree angles. They are found in squares, rectangles, and right-angled triangles. A circle is made by one line that is not straight but is curved.
If you drew a circle, rectangle, right-angled triangle, or cross in the circle, then the circle would contain perpendicular lines. But the circle itself would have no perpendicular lines.
A trapezium has no right angles therefore there are no perpendicular lines. If it had perpendicular lines, it would be a square or rectangle.
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.
Diamonds come in all shapes and sizes, which determine the number of perpendicular lines (assuming you are referring to the edges as the lines) so there is no one number of lines or perpendicular lines on a diamond.
A 9 sided nonagon normally has no perpendicular lines that meet at right angles
Perpendicular lines meet at 90 degrees
A circle can have perpendicular bisector lines by means of its diameter.
a circle
A circle
Perpendicular bisector lines intersect at right angles
just my opinion YES. many of them in fact. a line is not necessarily straight. all aroung the circle is an equal and opposite perpendicular curved line. IMO only
A circle !!!!!!
A circle.
Octagons have no perpendicular lines.
An octahedron has 7 perpendicular lines.
There are four perpendicular lines in a rectangle
Each of the four lines is perpendicular - to two of the other lines.
Not sure what a dimond is but a diamond has no perpendicular lines.
