How to use Set Vector Angle
- 1. Set the target angle and length. Choose Angle (degrees), the angle between the two generated vectors, and Length for how long each vector should be.
- 2. Set decimal places and wrap style. Choose Decimal places for how precisely the components are rounded, and pick Parentheses, Brackets, or None for how the vectors are displayed.
- 3. Generate and copy the vectors. The tool produces two vectors of your chosen length with exactly the angle you set between them. Copy them into a physics or graphics calculation.
When to use Set Vector Angle
Set Vector Angle generates a pair of vectors with a specific length and a specific angle between them, working backward from the usual direction of computing an angle from given vectors. Use it whenever you need example vectors that meet an exact angular relationship.
- Building a homework example with a known angle. A trigonometry or physics course wants example vectors with a clean angle like 60 degrees between them so students can verify the angle formula, and this generates matching vectors directly.
- Testing an angle-between-vectors function. You are validating a function that computes the angle between two vectors using the dot product, and want test vectors with a precisely known angle to confirm your formula's accuracy.
- Creating a force diagram at a specific angle. A mechanics problem needs two forces applied at a specific angle to each other, and generating them here provides exact component values ready to plug into a further calculation.
- Illustrating orthogonal or parallel vector examples. You want to demonstrate what perpendicular vectors, at 90 degrees, or nearly parallel vectors, at a small angle, look like in component form for a teaching example.
Examples
Two unit vectors 60° apart, one per line

About the Set Vector Angle tool
Set Vector Angle runs as plain JavaScript in your browser tab, with no server behind it. Create pairs with specific angles. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Math Tools section, 234 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 4 settings, including Angle (degrees), Length, Decimal places and Wrap, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Is Set Vector Angle free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Does the generator send anything to a server?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How do I get a different result?
Run the generator again. Each run is computed fresh on your device, and any options you change are applied to the next result immediately.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
