What else can I help you with?
what Navigation at sea requires the use of many points and lines to reference location and trajectory.What are the minimum points of reference needed to determine a trajectory (line)?
2 points
How many points do parallel lines have in common?
the parallel lines never intercept so they do not have any common points.
How many lines can be drawn through two fixed points?
In Euclidian or plane geometry, there can be only one line through two fixed points. Lines cannot actually be drawn; if you see it it is not a geometric line. If the points are on a curved surface as in a geometry that is non-Euclidian, then there can be infinitely many lines connecting two points.
How many rotational lines of symmetry does an equilateral triangle have?
Rotational symmetry is based on points of rotation not lines
If points A B and C all lie in a straight line but the other points are not on the line how many different lines can be drawn if each line contains at least two points?
2 lines, I believe.
How many lines are necessary to connect n points?
n - 1
If you have ten points How many line segments are needed to connect each pair?
45 points
How many lines are needed to connect one corner with each other corner in a regular pentagon?
5 straight lines are needed to construct a pentagon.
How many lines pass between two points?
If the line is straight, then only one line may connect two points.
How many line segments are needed to connect all pairs of 5 given points?
ten
In a regular pentagon how many lines are needed to connect each corner with every other corner?
10

2 points
How many points are needed to determine a straight line?
You need two points to determine a line. A single point can have an infinite number of lines passing through it.
If 16 points are arranged in a circle how many lines are needed to join every point to every other point once?
121
How many points do parallel lines have in common?
the parallel lines never intercept so they do not have any common points.
There are four equally spaced beads on a circle How many straight lines are needed to connect each bead with every other bead?
6
How many lines can be drawn out of 14 points on a plane with no 3 or more points collinear?
There are 91 lines.
