geometric figures
Triangles and circles
Geometric figures are shapes defined by points, lines, curves, and surfaces in space.
The term covers two-dimensional forms like circles, triangles, and squares, as well as three-dimensional objects like spheres, cubes, and pyramids.
In mathematics, geometric figures have precise properties—angles, lengths, areas, volumes—that can be measured and calculated: Students learned to identify basic geometric figures.
