Какая формула используется для расчета длины отрезка между двумя точками A(x1; y1) и B(x2; y2) на координатной плоскости?
AB = √(x2 - x1)² + (y2 - y1)²
AB = (x2 - x1) + (y2 - y1)
AB = (x2 + x1) / 2 + (y2 + y1) / 2
AB = |x2 - x1| + |y2 - y1|

Каковы формулы для расчета координат середины отрезка M(x0; y0) между двумя точками A(x1; y1) и B(x2; y2)?
x0 = (x1 + x2) / 2, y0 = (y1 + y2) / 2
x0 = x2 - x1, y0 = y2 - y1
x0 = (x1 * x2) / 2, y0 = (y1 * y2) / 2
x0 = x1 + x2, y0 = y1 + y2
