    Vertex form of a quadratic equation: A quadratic equation in the form of {eq}a(x-h)^{2} + k = 0 {/eq}, where a, h, and k are constants and (h, k) is the vertex. How to Convert Quadratic Equations ...

  6. Equation of a Parabola | Focus & Directrix Formula

    study.com/learn/lesson/parabola-focus-directix-formula-examples.html

    You now have an equation in terms of the vertex. The 'h' and 'k' are the x and y coordinates of the vertex. This is the parabolic equation in vertex form. From our example, the location of the ...

  7. Vertex Angle of an Isosceles Triangle | Definition & Examples

    study.com/learn/lesson/vertex-angle-isosceles-triangle-overview-steps-examples...

    The value for the vertex angle can always be calculated by subtracting the base angles from 180° using the general formula: 180° - 2B = A, where B refers to the base angle and A is the vertex angle.
