How many lines are determined by A B and C?
Three lines are determined by three points unless the points are all on the same line ( i.e. co-linear)
How many different lines are determined by 3 non collinear points?
Any three non-collinear points will define a single plane. A plane is composed of an infinite number of distinct lines.
How many different lines are determined by two points?
In classical or Euclidean plane geometry two points defines exactly one line. On a sphere two points can define infinitely many lines only one of which will represent the shortest distance between the points. On other curved surfaces, or in non-Euclidean geometries, the number of lines determined by two points can vary. Even in the Euclidean plane, two points determine infinitely many lines that are not straight!
How many lines are determined by 13 points no 3 of which are collinear?
There are 13*12/2 = 78 lines.
If points S O and N are collinear how many lines do they determined?
3
How many different lines are determined by three non-collinear points?
3
How many lines are determined by coplanar points a b c and d?
4*3/2 = 6 lines.
What is the least and maximum number of lines obtainable with 7 points?
depends on the position of the points if points are collinear, we have just only one line, the minimum number. If points are in different position (if any of the two points are not collinear) we have 21 lines (7C2), the maximum number of lines.
Points A B and C are collinear How many lines are determined by A B and C?
# 1
How many different lines are determined by three collinear points?
As long as at least two of them are different points, exactly one line.
What is the greatest number of lines determined by five points not three of which are collinear?
Since any two point must be collinear and must, therefore, define a line, the answer is 5C2, the number of combinations of two [points] out of five. This is 5*4/(2*1) = 10
What is the greatest number of intersection points possible with just 4 lines?
The greatest number of intersection points with just four lines is 6.
