Study Notes

Geometry Vocabulary - Chapter 8

Composite solids: Objects consisting of multiple types of solid geometries, combining their properties and measurements.
Cone: A 3D geometric figure featuring one circular base linked to a single vertex by a curved surface, resembling an ice cream cone.
Cylinder: A 3D shape characterized by two parallel, congruent circular bases connected by a curved surface, similar to a can.
Hemisphere: Half of a sphere formed when a plane intersects the sphere's center, divides it into two equal sections.
Lateral area: Represents the area of the surfaces of a solid figure, excluding the bases, essential for understanding the material needed for curved surfaces.
Nets: Flat, two-dimensional representations that can be folded to create a three-dimensional shape, helpful in visualization and construction.
Polyhedron: A solid figure composed of flat polygonal faces, edges, and vertices; examples include cubes and pyramids.
Similar solids: Solids that share the same shape and proportion across corresponding linear measurements, implying scale differences rather than shape alterations.
Sphere: A perfectly symmetrical 3D shape where every point on the surface is equidistant from the center, often likened to a basketball.
Total surface area: The overall area covering all surfaces of a 3D figure, including bases, critical for calculations involving paint or wrapping.
Volume: The measurement of the three-dimensional space a solid occupies, crucial for understanding capacity and storage.
