![]() What is the Axis of Symmetry Formula for Vertex Form? The formula used to find the axis of symmetry for a quadratic equation with standard form as y = ax 2 + bx + c, is: x = -b/2a. What is the Formula to Calculate the Axis of Symmetry for Standard Form? If the parabola is in vertex form y = a(x-h) 2 + k, then the formula is x = h. The axis of symmetry formula is given as, for a quadratic equation with standard form as y = ax 2 + bx + c, is: x = -b/2a. The symmetry cuts any geometric shape into two equal halves. The axis of symmetry formula uses the standard form of the quadratic equation as well as the vertex form. ![]() For example, a square has 4 and a rectangle has 2 axes of symmetry. The axis of symmetry is an imaginary straight line that divides the shape into two identical parts or that makes the shape symmetrical. A regular polygon of 'n' sides has 'n' axes of symmetry. The axis of symmetry is an imaginary line that divides a figure into two identical parts such that each part is a mirror reflection of one another. A regular polygon of 'n' sides has 'n' axes of symmetry.įAQs on Axis of Symmetry What is Axis of Symmetry in Algebra?. ![]()
