They may be defined in a number of different ways. One possible description is that they are conic sections.

Does a conic section have vertices?
No, a conic section does not have vertices. If it is a circle, it has a center; if it is a parabola or hyperbola, it has a focus; and if it is an ellipse, it has foci.
What shape is a possible cross section of a cone?
A point, a straight line, a circle, an ellipse, a parabola and half a hyperbola.
What are 12 geometry shapes?
Circle. Ellipse. Rectangle. Square. Triangle. Parallelogram. Trapezoid. Losenge. Deltoid. Pentagon. Hexagon. Parabola. That's twelve.
What is the midpoint of the parabola between the focus and the directrix?
It is the apex of the parabola.
Does a parabola have to have an x-intercept?
No, a parabola does not have to have an x-intercept. ex. -2(x-2)^2 - 4 is a parabola that has no x-intercept.
Is a wrecking ball a form of a parabola?
No, it is not. It is an arc of a circle.
Is a rainbow a parabola?
Sources vary. According to some, it is part (arc) of a circle, not a parabola. According to college professors and many proven resources online, it is a Parabola.
Is the arc de triomphe a parabola?
No, there is no parabola shape on the arc. The legs are parallel lines connecting to the arch which is an half-circle.
Can a circle touch a parabola at atmost 2 points?
Yes.
Why is a rainbow a parabola?
It has 2 pointsA2. It IS NOT a parabola. It is an arc of a circle. As many mountaineers or plane flyers know by looking down on the top of clouds and seeing a perfect circle of rainbow light surrounding their shadow.
What is mercury's orbit of the sun?
its orbit is not perfect circle, but is most eccentric of all planets,having eccentricity of 0.21 eccentricity means,the amount by which its orbit varies from perfect circle. 0 means circle and 1 means parabola. so mercury's eccentricity(0.21) is between circle and parabola, in fact, more closer to circle
What are the geometric characteristics of a circle ellipse parabola and hyperbola?
They are all conic sections.
Is a graph of a quadratic function always a parabola?
No. It can also be a circle, ellipse or hyperbola.
What is a parabola and ellipse?
A : A circle is a closed figure with eccentricity 1. Similarly, ellipse is also a closed fig with eccentricity less than 1 and parabola with greater than 1.
Is 5-y equals x2 plus x plus 1 a circle?
No, that's a parabola.
How do the characteristics and equations of a circle differ from those of a parabola?
In its standard form, the equation of a circle is a quadratic in both variables, x and y, whereas a parabola is quadratic in one (x) and liner in the other (y). A circle is a closed shape and comprises the locus of all points that are equidistant from one given point (the centre). A parabola is an open shape and comprises the locus of all points that are the same distance from a a straight line (the directrix) and a point not on that line (the focus).
What 2D shape looks like a squashed circle and no straight edges?
an ellipse, one of the four types of "conic sections": ellipse, circle, parabola, and hyperbola
