 * 6.1-Ortho. & Iso Drawings

Objectives -** By using dot paper, draw three-dimensional shapes - Understanding how to find orthographic projctions - Understanding how to find volume and surface area -** Orthographic Projection - Seeing the view of an object, by looking from the top, bottom, front, back, left, or right - Isometric Drawing - a picture from a 30° angle that bigger in the front and smaller in the back
 * Definitions

** - Understanding how to find the relationships in points,lines,planes,angles, and segments in three-dimensional space
 * 6.2- Relations between three-dimensional spaces
 * Objectives-** Define //polyhedron,//and //dihedral angle//

-Polyhedron- a closed three-dimensional figure that are made of polygons. these polygons are made of faces -Faces- the sides that make up the polyhedron -Edges-Edges are what connect the faces together. -Dihedral Angle-Formed by two planes with edges that are equal. Each plane is a face.
 * Definitions**


 * 6.3- Peaceful Prisms**

-// Understand the shapes of lateral faces of prisms - Use the diagonal measure of a right prism
 * Objectives-** Define //Prism, right prism,//and, //oblique prism

-** Prism- Contains a translated parallel plane, with quadrilateral faces connecting corresponding edges which makes a polyhedron There are many types of prisms. •Triangular Prism •Rectangular Prism •Pentagonal Prism •Hexagonal Prism [|PRISMS169]
 * Definitions

- Right Prism- A prism in which all the lateral faces are rectangles - Oblique Prism- A prism in which all the lateral faces are rectangles except one - Diagnol- A segment whose endpoints are vertices of two different faces of the ployhedron


 * Diagonal of a Right Rectangular Prism -** A right rectangular prism has the dimensions of L x W x H

- Be able to find the structures of three-dimensional coordinate system, which also includes the axes,octants, and coordinate planes - Use the distance formula to solve 3 dimensional problems
 * 6.4 - Finding Coordinates in 3-dimensions**
 * Objectives**


 * Octants -** a three dimensional system coordinate plane that is divided into eight sections.With only three plane coordinates

[|Distance Formula]
 * Coordiante Plane-** A section in which divides the octants. There are Three coordinate planes
 * yz plane
 * xz plane
 * xy plane
 * Distance Formula in Three Dimensions

6.6 - Perspective Drawing

Objectives -** you need to be able to identify and define the concepts of perspective drawing - you need to be able to create your own perspective drawing

- Sets of Parallel Lines** - In a drawing all the lines are parallel to each other but not to the picture, they meet at a vanishing point - **Lines Parallel to the Ground -** the line is on the ground and is parallel to the picture above
 * Theorems

- Vanishing Point -** The point where to parallel lines seemto meet on the horizon - **Two Point Perspective -** a drawing with two vanishing points
 * Definitions

~ **Note~** You can have as many vanishing points, like if you spell your name
