Create a Clean Angle Diagram
Angle Maker is for drawing and demonstrating an angle when you do not have a source image to measure. Enter degrees, drag the ray, use the wheel, press arrow keys, or choose a preset. The diagram updates immediately with the angle type and related values.
The page is useful for teachers, students, designers, and anyone preparing a simple geometry example. It keeps the angle visible as an SVG diagram, updates the URL parameter for sharing, and downloads a clean vector file without creating an account.
How to Draw an Angle
- Enter a degree value from 0 to 360, move the slider, or drag the ray handle on the diagram.
- Use presets for common examples such as 30, 45, 60, 90, 120, 180, 225, and 270 degrees.
- Copy a share link when another person should open the same angle, or download SVG when the diagram belongs in a worksheet, slide, or note.
Angle Types and Values
- Values below 90 degrees are acute, 90 degrees is right, values between 90 and 180 are obtuse, 180 degrees is straight, and values above 180 degrees are reflex.
- The summary shows complement, supplement, and reflex values where they are meaningful.
- Keyboard arrows adjust the angle by 1 degree, while Shift plus an arrow changes it by 10 degrees.
When to Use Angle Maker
- Create a quick diagram for an angle type explanation or homework example.
- Compare a generated angle with a measured angle from the main online protractor workspace.
- Download a simple SVG for classroom material, presentation slides, or geometry notes.
- Share a URL with an angle parameter so another browser opens the same diagram.
Drawing Is Different from Measurement
Angle Maker creates an idealized diagram. It does not inspect an uploaded image, detect real-world tilt, or verify that a physical object matches the drawing. Use the main online protractor for file-based measurement and the phone angle meter for live device tilt.
