Frequently Asked Questions

Q.What is the distance formula?

d = √[(x₂-x₁)² + (y₂-y₁)²] for 2D. For 3D: d = √[(x₂-x₁)² + (y₂-y₁)² + (z₂-z₁)²]. This is derived from the Pythagorean theorem.

Q.What is the midpoint formula?

Midpoint = ((x₁+x₂)/2, (y₁+y₂)/2). The midpoint is the exact center between two points.
