A line, ray, or line segment contains an infinite number of points.
Yes and they are the end points
yes, it may be the two plane intersect at one line or the two planes are coincident.
An angle is formed by at least three points of reference. The origin and two others in plain geometry. A line may be drawn from the point of origin and any other given point. Any other line may be drawn from the origin and any other point. The difference between these lines is referred to as an angle.
3 coplanar points may or may not be collinear. 3 collinear points must be coplanar.
Many different factors govern a poet's choices about line breaks.
Infinitely many planes may contain the same three collinear points if the planes all intersect at the same line.
Yes and they are the end points
If the line is straight, then only one line may connect two points.
Not enough information. Collinear means the points are on the same line. If you have any three points, they may, or may not, be on the same line.
None. In conventional geometry, any intersection of two planes defines a line, which is an infinite number of points. Many planes may intersect along a single line, or any pair of planes may intersect creating a unique line, but however they intersect, the number of shared points is infinite. If the the planes do not intersect (if they are parallel), then they share zero points.
One would say that this is the definition of a line, however, your question says "A straight path of points" and a line only have one point but no end. So it may be a line or may be considered infinite points.
In Euclidean geometry each line contains a minimum of an infinite number of points. In projective geometry, though, a line may have as few as two points.
Infinitely many. The trajectory of a typical space mission may be adjusted several hundred times and all these changes need to be accommodated in the set of points.
Yes. Infinitely may points.
To determine a trajectory line, only two points are needed. These two points can be used to calculate the slope, which represents the direction and angle of the trajectory. Additional points can be used to further refine the trajectory line and estimate its accuracy.
Two points. These may coincide if the line is a tangent to the sphere.
yes
