Answer:
The distance between two points, (18, 29), can be calculated using the distance formula from Euclidean geometry:
Distance = √((x2 - x1)^2 + (y2 - y1)^2)
Distance = √((18 - 18)^2 + (29 - 29)^2)
Distance = √(0^2 + 0^2)
Distance = √0
Distance = 0
So, the distance between the points (18, 29) and (18, 29) is 0 units.
