2 lines, I believe.
There are 16 possible triangles.
A chord is a straight line drawn through a circle which divides the circle into two parts. The line can be drawn anywhere in the circle EXCEPT the center where it becomes the diameter.

It is the radius
A series of 3 points will always determine a plane unless 2 or all 3 points are identical points (they have the same coordinates).If the idea is to have the three points determine oneplane, a unique plane, then three points will do that as long as none of them have the same spacial coordinates (have identical locations) or as long as the three points do not lie on a single line.If a straight line can be drawn through all three points, they will not form one unique plane either.
If the points are collinear, that means there's only one straight line. An infinite number of different planes can be drawn that contain one straight line.
The answer will depend on the relative positions of the points.
please answer
line segments
i think just one line, as its defenition of straight line
Yes. You can draw infinitely many straight lines from each point.
A straight line segment can be drawn joining any two points.
There are 16 possible triangles.
10 lines, but only if no three of them are collinear.
A concave polygon.
Angles on a straight line add up to 180 degrees.
