Endpoint Calculator
Result
Endpoint Calculator Find an endpoint given a midpoint and the other endpoint. — free online calculator.
Formula
- Endpoint Calculator calculates its result from Known Endpoint, Midpoint. It uses the formula Endpoint = 2×Midpoint − known Endpoint. Change any input to recalculate the result instantly.
- The main inputs are Midpoint x, Midpoint y, Known Endpoint x₁, Known Endpoint y₁. Enter them in the units and format shown in the calculator.
- Keep comparable quantities in compatible units whenever the formula combines or compares them.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Endpoint
- Midpoint x: 5
- Midpoint y: 6
- Known Endpoint x₁: 2
- Known Endpoint y₁: 4
Using Known Endpoint = 10, Midpoint = 3, the calculated result is -4.
