Formula
M = ((x1 + x2)/2 Symbol legend
| Symbol | Meaning | Unit | Copy |
|---|---|---|---|
M | Midpoint of the line segment | (x, y) | |
x_1, y_1 | First endpoint coordinates | (x, y) | |
x_2, y_2 | Second endpoint coordinates | (x, y) |
- Average the x-coordinates to get midpoint x-value.
- Average the y-coordinates to get midpoint y-value.
- Combine both averages as the midpoint coordinate pair.
Example
Worked example: points (1, 2) and (5, 8)
- 1 Midpoint x = (1 + 5)/2 = 3
- 2 Midpoint y = (2 + 8)/2 = 5
- 3 M = (3, 5)
The midpoint is (3, 5).
How
- Enter x1 and y1 for the first endpoint.
- Enter x2 and y2 for the second endpoint.
- Read the midpoint pair and copy it if needed.
Avoid
- Adding coordinates without dividing by 2.
- Averaging x with y values by mistake.
- Rounding midpoint coordinates too early for later calculations.
FAQ
Can midpoint coordinates be decimals?
Yes, midpoints are often decimals when coordinate sums are odd.
Does endpoint order matter?
No. Swapping points gives the same midpoint.
Can I use negative coordinates?
Yes, both positive and negative coordinates are supported.
