Angles and Degrees Worksheet Generator
Students classify angles as acute, right, obtuse or straight, and find a missing angle on a straight line. The classification depends on comparing to 90° and 180°, not on how long the rays are drawn.

What this sheet practices
Students classify angles as acute, right, obtuse or straight, and find a missing angle on a straight line. The classification depends on comparing to 90° and 180°, not on how long the rays are drawn.
Errors worth watching for
- Judging by the length of the rays instead of the opening.
- Calling a 180° angle obtuse.
How to use it
- Set the difficulty. Easy narrows the range; challenge adds missing values or extra steps.
- Choose how many questions and how many fit on a page. Ten per page is the most readable default.
- Print, or save as PDF. Replace any single question with the circular arrow if it does not fit your group.

About this generator
Are angles drawn to scale?
Approximately, but students should use the given degree measure when one is provided.
Is a protractor needed?
No. This sheet is about classification and angle relationships, not measuring with a tool.
Can I print this worksheet on A4 paper?
Yes. Switch Paper to A4 in the settings panel. The layout recalculates the page height and keeps 0.5-inch margins, so nothing is cut off.
Is an answer key included?
The generator always produces an answer key and worked solutions. They are part of the pass; the student sheet can be previewed and printed for free.
