Can we have a negative radius?
Can we have a negative radius?
There is no circle with a negative radius,because negative numbers do not exist in real life. You cannot say I have -1 pen,but you can say I got -1 pen meaning that you lost one. So “a circle having radius -1” is not a good statement. You can say the circle’s radius increased by -1 meaning it was reduced by 1.
Is the radius always positive?
Note: The radius, r, is always positive.
Can radius be negative in polar coordinates?
In the polar coordinate system, the ordered pair will now be (r, θ). The ordered pair specifies a point’s location based on the value of r and the angle, θ, from the polar axis. The value of r can be positive, negative, or zero.
Can a circle have a radius of 0?
To the best of my knowledge, there is nothing in the definition of a circle that specifies that its radius cannot be zero… however, a circle with radius zero loses a lot of the properties of circles. But a circle with a radius of zero cannot be scaled to any other radius.
Is it possible for a circle to have a radius of 0 Why or why not?
no, although in the complex plane, it would be y = ix and y=-ix. A circle with a radius of 0 is just a point.
Does a circle have 0 or infinite sides?
For this definition every point on a circle is an extreme point so it makes sense to say it has infinitely (uncountably!) many corners. Though the notion of side is not as good. If the definition is line segment joining two vertices then the answer would be 0 for the circle.
What is a 1 million sided shape called?
megagon
What is an infinite sided shape?
In geometry, an apeirogon (from the Greek words “ἄπειρος” apeiros: “infinite, boundless”, and “γωνία” gonia: “angle”) or infinite polygon is a generalized polygon with a countably infinite number of sides. Apeirogons are the two-dimensional case of infinite polytopes.
What do you call a 7 sided shape?
A five-sided shape is called a pentagon. A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides… Polygon Names. The names of polygons are derived from the prefixes of ancient Greek numbers.

What do you call a 20 sided shape?
Convex, cyclic, equilateral, isogonal, isotoxal. In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon’s interior angles is 3240 degrees.

What do you call a 12 sided shape?
In geometry, a dodecagon or 12-gon is any twelve-sided polygon.
