What is the Endpoint Calculator?
The Endpoint Calculator determines the coordinates of an endpoint of a line segment when the midpoint and starting point are given. This tool is useful in geometry for finding the missing end of a line segment when you know its midpoint. It helps in various applications including geometry problems, graph plotting, and spatial analysis.
Formula
The formula for finding the endpoint B = (x₂, y₂) when the midpoint M = (x, y) and starting point A = (x₁, y₁) are known is:
x₂ = 2x - x₁
y₂ = 2y - y₁
How to Use the Endpoint Calculator
To use the Endpoint Calculator, first enter the coordinates of the starting point (x₁, y₁) and the midpoint (x, y) in their respective input fields. Click the "Calculate" button to compute the coordinates of the endpoint (x₂, y₂). The result will be displayed in a table below. To clear the inputs, click the "Clear" button.

Frequently Asked Questions
What is the midpoint of a line segment?
The midpoint of a line segment is the point that divides the segment into two equal parts. It is found by averaging the x-coordinates and y-coordinates of the segment’s endpoints.
How do you find the coordinates of a midpoint?
To find the coordinates of the midpoint, use the formula: (x₁ + x₂) / 2 for the x-coordinate and (y₁ + y₂) / 2 for the y-coordinate, where (x₁, y₁) and (x₂, y₂) are the endpoints of the segment.
Can the Endpoint Calculator be used for 3D coordinates?
No, this calculator is specifically for 2D coordinates. For 3D coordinates, additional dimensions and formulas are required.
What if I only have one endpoint and the midpoint?
You can still use the Endpoint Calculator. Input the known endpoint and midpoint, and the calculator will determine the coordinates of the missing endpoint.
What are the practical applications of endpoint calculations?
Endpoint calculations are useful in geometry, computer graphics, engineering, and any field that involves spatial analysis and design.
How accurate is the calculator?
The calculator provides precise results based on the input values. Ensure that the values entered are accurate to get correct results.
Can I use the calculator for plotting graphs?
Yes, you can use the results from the calculator to plot points and segments on a graph for visual representation and analysis.
What if I enter incorrect values?
Incorrect values will result in inaccurate endpoints. Ensure all inputs are correct before performing the calculation.
Is there a limit to the values I can enter?
There is no specific limit, but extremely large or small values might affect the accuracy of calculations or result in overflow errors.
How can I improve the accuracy of the results?
Double-check your input values and ensure they are correctly entered. Precision in input values directly affects the accuracy of the result.
