1. 1-1: Nets and Drawings
Visualizing Geometry

2. Nets vs. Solids Geogebra Nets
Cube, Rectangular Prism, Cylinder, Cone, Octahedron
Net – a 2D diagram that shows all the surfaces of a 3D figure
Net of cylinder
3D cylinder

3. Isometric Drawings
Isometric Drawing – a drawing that shows a corner view of a three- dimensional figure.
Slanted lines represent depth
Isometric Dot Paper can be used to draw solids

6. Drawing Nets
Draw a net for the following figure.
3 in.
10 in.
4 in.

7. Take Home Message 3D shapes can be view as 2D shapes
Nets will help us solve for surface area
Geometry is all around us
