In the video, a person is seen drawing a triangle on a piece of paper. The triangle is filled with smaller triangles, and the person is using a green marker to fill in the smaller triangles. The person's hand is visible as they draw, and the paper is placed on a flat surface. The video is shot from a top-down perspective, and the focus is on the drawing process. The person's hand moves steadily as they fill in each smaller triangle, and the green marker leaves a vibrant color on the paper. The triangle is drawn with precision, and the smaller triangles are evenly spaced within the larger triangle. The video ends with the completed drawing of the triangle filled with smaller triangles.
