Solid Geometry

1. Solid Geometry

2. Student Expectations • 7th Grade: 7.3.6C Use properties to classify three-dimensional figures, including pyramids, cones, prisms, and cylinders.

3. 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

4. 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

5. 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

6. 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

7. 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

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

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

10. Prisms & Pyramids

11. Three Dimensional Figures with Curved Surfaces
