The icon Rotate Left is a circle. It starts on the left side at the bottom with seven lines that start small and get longer. The eighth line is the longest and continues all the way around ending with an arrow.
This Rotate Left icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 6,000 icons, all in the same style and quality.
