Midpoint Formula (Leaving Cert Mathematics): Flashcards

Exact centre point of a line segment

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

The $x$-coordinates and $y$-coordinates of endpoints

Divide a line segment into two equal parts

Identify the center of a geometric figure

It's the average of coordinates of the two points

$(3, 5)$

$(1, 2)$

Average the $x$-coords and $y$-coords of the two endpoints
