Visual Euclidean Distance, Midpoint & Perpendicular Bisector Plane
For points $A(x_1,y_1)$ and $B(x_2,y_2)$ in $\mathbb{R}^2$, the Euclidean distance is $d(A,B) = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}$ and the equidistant midpoint is $M = \left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)$.

Key Analytical Takeaways
- 01The Euclidean distance formula is simply the Pythagorean theorem applied to coordinate differences $a = |\Delta x|$ and $b = |\Delta y|$.
- 02With default $(-5,-3)$ and $(7,6)$, $\Delta x = 12$ and $\Delta y = 9$, forming a $(12, 9, 15)$ right triangle with exact distance $d = 15$.
- 03The midpoint $M$ bisects segment $AB$ into two congruent halves of length $d/2$.
Frequently Asked Questions
Does the order of points (A to B vs. B to A) change the distance or midpoint?+
No. Squaring (x₂ − x₁)² eliminates any negative sign in the distance formula, and addition (x₁ + x₂)/2 is commutative in the midpoint formula.
What is Manhattan (L₁) distance compared to Euclidean (L₂) distance?+
Manhattan distance is |Δx| + |Δy| (walking along grid streets), whereas Euclidean distance √(Δx² + Δy²) is the straight-line diagonal flight path.
How do you find the equation of the perpendicular bisector of segment AB?+
Pass a line through midpoint M = ((x₁+x₂)/2, (y₁+y₂)/2) using the negative-reciprocal slope m_perp = −(x₂ − x₁) / (y₂ − y₁).
