The image shows a triangle with three dots representing vertices and lines representing sides. Below the triangle are two checkboxes with labels in Russian. The first checkbox is labeled 'вершины' (vertices) and the second is labeled 'стороны' (sides). There's also a progress bar with '83%' indicating a discount or progress, and a timer showing '04:04'. A user named 'Анна О.' is mentioned with a score of '0'. The question is to identify what the elements represent.
