The T, U, and V are symmetrical, but they each have only one line of symmetry. None of these letters has two lines of symmetry. Now think about the last letters of the alphabet!
Since there are an infinite number of lines through the center, the circle has an infinite number of lines of symmetry.
A set of points has line symmetry if and only if there is a line, l, such that the reflection through l of each point in the set is also a point in the set. (May also be referred to as reflectional symmetry.) Certain figures can be mapped onto themselves by a reflection in their lines of symmetry.
