Find the distance, midpoint, or a ratio-dividing point between two coordinates — free and instant.
Three related coordinate-geometry calculations for two points: the distance between them (via the distance formula, derived from the Pythagorean theorem applied to the horizontal and vertical gaps), the midpoint (the simple average of both coordinates), and the section formula — the point that divides the segment in a given ratio m:n, either internally (between the two points) or externally (beyond one of them, on the extended line).
The midpoint is really just a special case of internal section division at a 1:1 ratio, but it's common enough to show on its own without needing to set the ratio first.
Internal division finds a point between the two given points. External division finds a point outside the segment, on the line extended beyond one end — the formula is the same idea with a subtraction instead of an addition.
Yes — m and n just need to be positive numbers; they don’t need to be integers.
Yes exactly — shown separately here since it’s the far more commonly needed case.
