The answer depends on what H is supposed to represent.
1. Given any line, there are at least two points on the line. Call them A and B. 2. Given any line, there exists at least one point in the plane that is not on the line. Call that point C. 3. Given any two points (A and C and, then B and C) there exists a straight line joining them. The point C is not on AB so AB and AC are distinct. Similarly, AB and BC are distinct so that there are three lines that meet, in pairs, at three vertices - and that is a triangle.
That would depend on where you looked at it from. All constellations depend on where they are seen from. If our planet were orbiting around a different star, most, if not all the constillations would look different. If you are on the Earth, it's not in any constellation.
The line goes through the midpoint, which is halfway between points. The distances are equal to each other, and proves that they are equidistant.
There are no planes containing any number of given points. Two points not the same define a line. Three points not in a line define a plane. For four or more points to lie in the same plane, three can be arbitrary but not on the same line, but the fourth (and so on) points must lie in that same plane.
The shortest route between two points is a straight line. But since the Earth is round (try bending a ruler along the surface of a basketball or something), the shortest route between two points on a globe will look like a curve when seen o a flat map. And since people wanted Titanic to cross the Atlantic as fast as possible, the shortest route possible is also the most northern route, and she ended up in iceberg territory.

Not sure what a loni is. On a plane surface, a curved line between any two fixed points is longer than the straight line joining the same points.
Line joining the points of equal variation is known as Iogonic line andthe line joining the points of zero variation is know as Agonic line.
A secant line.
A plane is a flat, closed figure.a flat surface on which a straight line joining any two points on it would wholly lie:
an imaginary line, joining the equal elevations of the points
Plain surveying means the survey in which earth surface is considered as to be flat or plain i.e. its curvature is ignored. Geodetic survey is the survey in which curvature of the earth is taken into count and then surveying is done.
Points cannot be parallel to other points. A straight line joining two points is parallel to a straight line joining another pair of points if the gradient (slope) of the two lines is the same.
They are coplanar if the line joining any two of them intersects the line joining the other two.
The perpendicular bisector of the straight line joining the two points.
A plane is a flat, closed figure.a flat surface on which a straight line joining any two points on it would wholly lie:
