Solid Geometry

2
**Student Expectations 7th Grade:**

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

3
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.

4
**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.

5
Base The lowest part. The surface that a solid object stands on, or the bottom line of a shape such as a triangle or rectangle.

6
**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.

7
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.

8
Cylinder A cylinder is a solid object with: * two identical flat circular or elliptical ends * and one curved side.

9
Cone A solid (3-dimensional) object that has a circular base and one vertex
