What are shapes?
Shapes are geometric figures described mathematically.
Classification of shapes can be based on the larger shape
they fit inside.
Two-dimensional shapes like circles fit inside flat planes,
while three-dimensional objects like cubes cannot fit into a
plane due to their non-flat nature.

3 Dimensional Shapes
Three-dimensional shapes possess four
distinguishing properties: faces, vertices, edges,
and volume.
These properties help differentiate between two-
dimensional and three-dimensional shapes, and
also identify specific types of three-dimensional
shapes.

A map is a graphic
representation of a portion of
the earth's surface, drawn to
scale and viewed from above.
It employs colors, symbols,
scales, and legends to depict
features found on the ground.
