# Reflect a Point Over a Point Calculator

**Introduction**

Reflecting a point over another point is a fundamental concept in geometry, and having a calculator to effortlessly perform such calculations can be a valuable tool. In this article, we will introduce a Reflect a Point Over a Point Calculator using HTML and JavaScript, allowing users to quickly determine the coordinates of a reflected point.

**How to Use**

To use the Reflect a Point Over a Point Calculator, simply input the coordinates of the original point and the point of reflection. Click the “Calculate” button to obtain the reflected point’s coordinates.

**Formula**

The formula for reflecting a point (x, y) over another point (a, b) is as follows:

Where:

- (
*x*′,*y*′) are the coordinates of the reflected point. - (
*x*,*y*) are the coordinates of the original point. - (
*a*,*b*) are the coordinates of the point of reflection.

**Example**

Let’s consider an example: reflecting the point (3, 4) over the point (1, 1).

So, the reflected point is (-1, -2).

**FAQs**

**Q: How do I use the calculator?**

**A:**Simply input the coordinates, click “Calculate,” and the reflected point will be displayed.

**Q: Can I reflect any point over any other point?**

**A:**Yes, the calculator is designed to work with any valid coordinates.

**Q: What if I don’t know the formula?**

**A:**The calculator automates the formula, so you don’t need to worry about it.

**Q: Are there any limitations to the calculator?**

**A:**The calculator assumes valid numerical inputs and may not handle non-numeric or invalid entries.

**Conclusion**

In conclusion, the Reflect a Point Over a Point Calculator simplifies geometric calculations, providing users with an efficient means of determining the reflected coordinates. Whether you’re a student, educator, or professional, this tool can streamline your geometric reflections.
