How is the distance from a point to a straight line in plane geometry defined? (1) Positional relationship between point and straight line There are two kinds of positional relationship between a point on a straight line and a point outside a straight line. Whether the coordinates of the point satisfy the straight line equation to judge the positional relationship between the point and the straight line. (2) The formula for the distance between two points A (a1, b1) and B (a2, b2)
