There's an infinite number of lines of symmetry in a circle.
The number of square corners in a circle is infinite because it has no definite angle.
A circle has an infinite number of lines of symmetry. Any chord of the circle that passes through its center will be a line of symmetry. And there are an infinite number of lines that can be drawn through the center of the circle, the length of which is equal to the diameter of the circle.
An oval has no exterior angles (or an infinite number depending on your point of view !)
a circle?
Yes.
A circle has an infinite number of angles of rotational symmetry.
An infinite number, because the number of angles available is infinite.
The size of the circle is immaterial, there are an infinite number of plottable angles.
I may be wrong, but since a an oval has no sides, like a circle, then it should have and infinite number. I think any shape that has no sides, angles, corners, etc. has an infinite number. (This applies to 2D figures)
Technically there are an infinite number of radii in a circle. A radius is a line from the center of the circle to a point on its edge, and since there are an infinite number of points on a circle's edge there are an infinite number of radii.
There are an infinite number of points on the circumference of a circle and an infinite number of points on a semi-circle so the answer to your question is "An infinite number of pairs of points."
One side and no angles. Unless you define a side as having to be straight line, then it is no sides. If a side can be a curved line by definition, then the number of sides is not an infinite number. If a side can have any curve then a circle has one side which connects into itself.
A circle has an infinite number of lines of symmetry. Any chord of the circle that passes through its center will be line of symmetry. Since there is an infinite number of chords, there is an infinite number of lines of symmetry.
The radius of a circle or a sphere has infinite number of points.
Since a sphere has an infinite number of side and angles, we can easily conclude that the new drawing for a sphere is a simple circle. The other new drawings do not have an infinite number of sides. Hence, They look 3D
Generally, no. All circles contain an infinite number of chords, as a chord can be created between any two points on the circle. With an infinite number of points on the circle we can create an infinite number of chords.
