Distance/Midpoint Formula (Junior Cert Mathematics): Flashcards

$\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Find how far apart two points are on the Cartesian Plane

$\left(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}\right)$

Point exactly halfway between two points on a line segment

Label the points as $x_1$, $y_1$, $x_2$, $y_2$

To avoid mistakes, especially with negative numbers

Brackets, exponents, then addition

$5$ units

$(5, 5)$

Add both x-coordinates and divide by $2$

Add both y-coordinates and divide by $2$

Distance between points $A$ and $B$
