Check if three points are collinear
WebIf the determinant is zero, then the points are collinear. And similarly, if the points are collinear, then the determinant is zero, where we assume we have three distinct points. And to see why this is true, we can recall the … WebIf ab + bc = ac then the three points are collinear. The line segments can be translated to vectors ab, bc and ac where the magnitude of the vectors are equal to the length of the respective line segments mentioned. By example of the points you've given in response to Naveen. a (2, 4, 6) b (4, 8, 12) c (8, 16, 24) a b ¯ = 56 b c ¯ = 224 a c ¯ = 504

WebJul 6, 2024 · 1 Use dot product. Let a, b, c be three points. If all three points lie on the same line, then the vector b-a and the vector c-a will have a dot product of b-a c-a . This is due to the fact that cos (angle (bac))=dot (b-a,c-a)/ (mag (b-a)*mag (c-a)). If they are collinear, then the angle is zero. WebMar 24, 2024 · The condition for three points , , and to be collinear can also be expressed as the statement that the distance between any one point and the line determined by the other two is zero. In three dimensions, this means setting in the point-line distance (5) giving simply (6) where denotes the cross product .
