( 𝑎+𝑐 2 , 𝑏+𝑑 2 ) Finding Midpoint The midpoint of a 2-Dimensional line segment with endpoints (a,b) and (c,d) can be found using the formula ( 𝑎+𝑐 2 , 𝑏+𝑑 2 )

Examples

Finding endpoint, given one endpoint and the midpoint

Finding Distance In 1-Dimension, distance was calculated as 𝑏−𝑎 In 2-Dimensions, distance is given by d= (𝑥 2 − 𝑥 1 ) 2 + (𝑦 2 − 𝑦 1 ) 2

Example What is the distance between (0,3) and (0,8)?
