Here is a parabolic curve example. According to mathematics, a plane curve with a U shape with a mirror-symmetry is a parabolic curve. A parabola has a point which is called a focus and a directrix. Any point present on the directrix line is equidistant from the focus of the parabola. In parabolic curve representation, consider the X-axis and Y-axis. The shape of curves on both sides of the Y-axis is the same. They are like mirror reflections. This property of the parabolic shape is known as symmetry.
