Objectives** //>Take the "isometric dot paper" and draw "3-D" shapes with cubes. >develop an understanding of orthographic projection. >develop a basic understanding of volume and surface area.
 * Drawing funky solid shapes section 1

[|Isometric Drawing]//:the horizontal lines of an object are represened by lines that form 30 degree angles with a horizontal line in the picture.

[|Orthographic projection]//:// A view of an object in which points of an object are projected on the picture plane along lines perpendicular to the picture plane.

//>Define:"polyhedron" >Identify the relationships between points,lines,segments,planes,and angles in 3-D space. >Define:"dihedral angle"//
 * Spatial Relationships Rock section 2!**
 * Objectives**

Solids:Closed spatial figures [|Polyhedron]:A closed spatial figure built up with polygons -Face:The polygons in the polyhedron. [|nick was here <-] -Edge:Where the faces intersect. -Vertice:vertices of the face=The vertices of the polygon. [|Dihedral Angle]:The figure by two half planes with an edge in common. -Face:each half-plane -Edge:Common edge of the half planes. Two planes are parallel only if they never intersect.
 * Parallel Planes**
 * BY:ARFI**

//The only time that a line is perpendicular to a plane at a given point is if it is parallel to a line in that plane.// //**A Line Parallel To A Plane** The one and only time a line that is not in a given plane is parallel to the plane is if it was parallel to line in that plane.//
 * A Line Perpendicular To A Plane**
 * //By:NATHAN SNIDER

Measure Of A Dihedral Angle//** //The measure of a dihedral angle is the measure of an angle formed by two lines that never end or "**rays**" that are on the faces and that are perpendicular to the edge.


 * Totally Cool Prisms section 3!**//

//>Define Prism,Right Prism,And Oblique Prism. >Look at the shapes of lateral faces of prisms. >Use the diagonal measure of a right prism to solve problems.// P[|rism]:A polyhedron that has a polygonal region and its translated image on a parallel plane,with quadrilateral faces connecting corresponding edges. -Base:The faces formed by the region called polygonal and its image. -Lateral Faces:The remaining faces which are quadrilaterals. -Lateral Edges:The edges of the lateral faces that are not edges of either base. [|Right Prism]:A prism that all of the lateral faces are rectangles. [|Oblique Prism]:has at least one nonrectangular lateral face. Diagonal Of A Polyhedron:A segment thats endpoints are vertices of two different faces of the polyhedron.
 * Objectives**

//**Diagonal Of A Right Rectangular Prism** In a right rectangular prism with dimensions L×W×H,the length of a diagonal by d=square root of:L^2+W^2+H^2.

//>Identify the features of a 3-D coordinate system including the axes,octants and coordinate planes. >Use the distance formula in three dimensions to solve problems.// [|Right-Handed System]:Using your right hand your index finger reprensents the x-axis,your middle finger the y-axis,and your thumb the z-axis. [|Octants]:The x-,y- and z- axes divide sapce into eight octants. [|Coordinate Plane]:three types of planes which are xy,xz,and yz.

 * BY:HANAAN**

//The distance,d,between the points (x1,y1,z1) and (x2,y2,z2) is given by d=the square root of:(x2-x1)2+(y2-y1)2+(z2-z1)2.//
 * Distance Formula In Three Dimensions**

//The midpoint of a segment with endpoints at (x1,y1,z1) and (x2,y2,z2) is the point (__x1+x2÷2__, __y1+y2÷2__ , __z1+z2÷2)__//

BY:RACH ROB Objectives** //>Identify and define the basic concepts of perspective drawing. >Use your knowledge of the basic concepts to make your own perspective drawings.//
 * Lets Do Perspective Drawing section 6!

Vanishing Point:The point when it seems that the parallel lines are meeting which is usually the horizon.
 * BY:CRESK

Theorem:Sets Of Parallel Lines** //In a perspective drawing,all lines that are parallel to each other,but not to the picture plane,meet at a single point known as the vanishing point.//

//In a perspective drawing,a line that is in the plane of the ground in the drawing and is not parallel to the picture plane will meet the horizon of the drawing.Any line parallel to this line will meet the horizon of the drawing at the same point.
 * Theorem:Lines Parallel To The Ground**
