A cylinder has an infinite number of lines of symmetry (because a circle has an infinite number of lines of symmetry).
two of the faces of a cylinder are circles circles have an infinite number of lines of symmetry therefore cylinders have an infinite number of planes of symmetry
circle
A ball (sphere) has an infinite number lines of symmetry.
That number is infinite. Every diameter of a circle is a line of symmetry.
O
An infinite number
i was going to ask this quiestion
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.
A cylinder has an infinite number of lines of symmetry (because a circle has an infinite number of lines of symmetry).
It has rotational symmetry of infinite order as well as an infinite number of axes of symmetry.
A sphere has an infinite number of lines of symmetry
two of the faces of a cylinder are circles circles have an infinite number of lines of symmetry therefore cylinders have an infinite number of planes of symmetry
A circle
There are an infinite number of lines of symmetry in a circle, as any diameter will be a line of symmetry and there are an infinite number of angle measure for that line to pass through.
A circle has an infinite number of lines of symmetry
There's an infinite number of lines of symmetry in a circle.
