About the Protractor Semicircle Ruler black outline icon
A half-circle protractor rotated so its straight edge runs from the upper left to the lower right, with short degree ticks spaced around the curved rim and a second inner arc marking the measuring window. It stands for angles, geometry and technical drawing. Use it on math learning apps, school supply shops, engineering course pages, design tool banners and classroom worksheets.
The tilt gives the flat baseline a diagonal that fills the square frame better than an upright version, and the inner arc keeps the body from looking solid. It pairs with ruler, compass and set square icons. Below 32 pixels the tick marks blur, so scale up.
This is the black outline version of the protractor semicircle ruler icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
