What is the midpoint formula?

For two points A(x1, y1) and B(x2, y2), the midpoint M is ((x1+x2)/2, (y1+y2)/2). In 3D, you also average the z coordinates: ((x1+x2)/2, (y1+y2)/2, (z1+z2)/2).

Can this calculator handle negative coordinates?

Yes. Enter negative values with a minus sign (e.g. -3.5). The formula works the same for any real number.

Does it support decimal coordinates?

Yes. You can enter any decimal number such as 1.5, -2.75, or 0.333. Results are shown to 6 decimal places when needed.

What is the difference between 2D and 3D mode?

In 2D mode you provide x and y coordinates only. In 3D mode you also provide a z coordinate, which is useful for points in three-dimensional space.

Why is the midpoint always equidistant from both points?

By definition, averaging the coordinates places the midpoint exactly halfway along each axis, making the Euclidean distance from the midpoint to either endpoint identical.
