The place where two points meet is known as an intersection in math.
A two-dimensional surface on which points are plotted and located by their x and y coordinates
Six: top, bottom, two ends and two sides.
Yes, on a plane surface (a flat sheet of paper, for example).
The great circle is the intersection of a sphere and any plane passing through its centre. Given two distinct points on the surface of a sphere, those two points and the centre of the sphere define a plane. [If one of the points is at the antipodes of the other, an infinite number of planes are defined.] The great circle is the circle formed when that plane meets the surface of the sphere.
A tooth with two cusps is called a bicuspid or premolar.
bicuspid? bi?
it is called bicuspid
The word part meaning two is "bi" so it would be the bicuspid.
which are two basic point of reference on the surface of the earth

The shortest route between two points on the surface of a planet, when routes are limited to the planet's surface, is the arc of the great circle that connects the two points. The shortest route between two points anywhere, without regard to intervening matter or energy preventing the route from being followed, is always the line connecting the two points.
It's possible to have two different cavities in one tooth. It's also possible that it is just one cavity, but it is on two surfaces of the tooth. Each tooth has five surfaces. Each surface added to a filling will be more money.
Tthe one surface means that the dentist only worked on one surface/side of your tooth, let's say the front part, if it is two surface he worked on 2 sides, the front and one side of your tooth, If it is 3 surfaces he worked on front, back and one side of the tooth
The number of edges in a smokestack will depend on how you look at it. It probably has two edges to it, and here's why. A smokestack is basically a solid shape that is a hollow cylinder with a certain thickness. It has an inner and outer surface, and a surface on the top. We can ingnore the bottom surface or not, depending on what you are thinking of. Now let's focus. The top has two edges. There is the outer edge of the top of the cylinder, which divides the outer surface from the top surface. Then there is the inner edge of the top of the cylinder, which divides the inner surface from the top surface. So a smokestack has two edges. If you want to count the bottom (which you probably don't), add two more. Otherwise there are a pair of edges formed on the top surface of the cylinder, one around the outside and one around the inside.
We have several reference points on the Earth's surface, for our convenience. The North and South Poles are a couple. The choice of Greenwich as the zero longitude, and of the International Date Line are another two. These points have no specific feature on the surface, they are decided on for the convenience of the users.
for a baby either the top two or bottom two front teeth grow first
