College Math CLEP Prep Practice Exam

A square has four lines of symmetry. This means that if you were to fold the square along these lines, the top and bottom halves would match up perfectly. Option A is incorrect because two lines of symmetry would only result in two matching halves. Option C is incorrect because six lines of symmetry would result in six matching halves, which is not possible for a square. Option D is incorrect because eight lines of symmetry would result in eight matching halves, which is also not possible for a square.
