Student Expectations

  • 7th Grade:

    7.3.6C Use properties to classify three-dimensional figures, including pyramids, cones, prisms, and cylinders.


Three dimensions

Solid Geometry is the geometry of three-dimensional space

It is called three-dimensional, or 3D because there are three dimensions: width, depth and height.

Three Dimensions


Polyhedron

A geometric object with flat faces and straight edges.

a polyhedron is a three - dimensional figure made up of sides called faces, each face being a polygon.

Polyhedron


Solid geometry

The lowest part. The surface that a solid object stands on, or the bottom line of a shape such as a triangle or rectangle.

Base


Prism

A solid object that has two identical ends and all flat sides.

The cross section is the same all along its length.

The shape of the ends give the prism a name, such as "triangular prism“

It is a polyhedron.

Prism


Pyramid

A solid object where:* The base is a polygon (a straight-sided shape)* The sides are triangles which meet at the top (the apex).It is a polyhedron.

Pyramid


Cylinder

A cylinder is a solid object with:* two identical flat circular or elliptical ends* and one curved side.

Cylinder


Solid geometry

A solid

(3-dimensional) object that has a circular base and one vertex

Cone
