About the Protractor Half Circle black filled icon
A semicircular protractor is shown tilted on its straight edge, with short degree tick marks spaced around the curved rim and an inner arc marking the reading window. It represents angle measurement, geometry and technical drawing. Use it for math and geometry lessons, e-learning course cards, school supply shops, CAD and design tool palettes, and engineering or architecture presentations.
The diagonal placement fills the square frame better than a flat semicircle would and keeps the tick marks evenly visible along the arc. It groups well with ruler, compass, set square and pencil icons in a stationery set. Use 32 px or larger so the degree marks read as a scale instead of noise.
This is the solid black filled version of the protractor half circle icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
