Geometry/Chapter 17

Coordination Geometry can be used to find the midpoint of two coordinates. For example (8,5)(4,2). The formula is[x+x(2nd)] divided by 2. ,[y+y(2nd)] divided by 2. For this example this would be: [(8+5) divided by 2],[(4+2) divided by 2]. This equals (6,3.5), which is the midpoint between these two coordinates.
