Coordinates and Ratio (AQA GCSE Maths): Flashcards

Portion of a line between two specific endpoints

Point exactly halfway between two endpoints

Add x-coordinates of endpoints, divide by 2

Add y-coordinates of endpoints, divide by 2

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

How far along the segment a point is positioned

4 parts

Calculate differences, apply ratio, add to starting coordinates

Ratio is $1:1$

Proportional relationships
