3 points are given: A, B, C. Find the distance from point A to the midpoint of segment BC.

Based on the data, it turns out that point A is higher than points B and C (BC are on the same line and form a segment). thus, a visual triangle is formed. Now you need to lower the perpendicular from point A to the middle of the segment BC. It turns out a segment, one cell long. Thus, the distance from point A to the middle of the segment BC is also 1 cell.
