Finding the Midpoint of a Segment (Grades 6–8)

The midpoint is the point exactly halfway between two points. Find it by averaging the x-coordinates and averaging the y-coordinates: midpoint = ((x₁+x₂)/2, (y₁+y₂)/2). The midpoint of (2, 4) and (6, 8) is ((2+6)/2, (4+8)/2) = (4, 6).

What it is

Understanding finding the midpoint

The midpoint is the point exactly halfway between two points. Find it by averaging the x-coordinates and averaging the y-coordinates: midpoint = ((x₁+x₂)/2, (y₁+y₂)/2). The midpoint of (2, 4) and (6, 8) is ((2+6)/2, (4+8)/2) = (4, 6).

Key Idea

The midpoint is the point exactly halfway between two points. Find it by averaging the x-coordinates and averaging the y-coordinates: midpoint = ((x₁+x₂)/2, (y₁+y₂)/2). The midpoint of (2, 4) and (6, 8) is ((2+6)/2, (4+8)/2) = (4, 6).
