The axis of symmetry is a straight line that divides an object into two identical parts, thus creating one part as a mirror image of another. Folded along the axis of symmetry, the two parts become superimposed. In terms of symmetry, the mirror line is the straight line. The horizontal, vertical, or slanting line can … Read more
Parabolas are graphs of quadratic functions in mathematics. A parabola is a projective curve of a circle, according to Pascal. Galileo described a path called a parabolic path that is followed by projectiles falling under uniform gravity. In most cases, physical motions of bodies follow a curvilinear path in the shape of a parabola. Parabolas … Read more
