It sounds like this describes the conic section which is 2 straight lines intersecting at the origin [degenerate form of a hyperbola], but I may be misunderstanding the phrasing of the question.
It is the cross-section of the figure by the plane.
the intersection of the two sides of an angle is called its
If the question refers to the axes of a graph, their intersection is called the "origin".
A line. When two planes intersect, their intersection is a line.
A cross section of a cylinder along its length is called a rectangle. When a cylinder is cut along its length, the resulting shape is a rectangle with a length equal to the circumference of the cylinder and a height equal to the height of the cylinder. The area of this rectangle represents the lateral surface area of the cylinder.
A parabola is the figure formed by the intersection of a circular cone and a plane that lies parallel to the edge of the cone. (the cone does not have to be a right [90°] circular cone).
The intersection forms a hyperbola.
The coloured section of your eye is called the 'iris'. And the black circular ring is called the pupil.
It is the cross-section of the figure by the plane.
The intersection of the water table with the Earth's surface, from which water flows continuously, is called a spring. Springs occur when groundwater reaches the surface naturally through a point of discharge.
Circles, ellipses, parabolas, and hyperbolas are called conic sections because they can be obtained as a intersection of a plane with a double- napped circular cone. If the plane passes through vertex of the double-napped cone, then the intersection is a point, a pair of straight lines or a single line. These are called degenerate conic sections. Because they are sections of a cone or a cone shaped object.
Yes. An annulus is a circular disc with a concentric circular disc cut out of it.
A figure with 2 circular bases and one curved surface is called a cylinder. Examples are food cans.
A paraboloid.
The moons surface has mountainous highlands and large circular plains. The circular plains are called Maria. The mountain has heights up to 25000 feet.
It is a cone.
The word "base" is just fine for this purpose.
