objectives..** 1. use isometric dot paper, to draw three dementional shapes composed of cubes. //2. develop an understanding of orthographic projection.// __3. devolop a basic understanding of volume and surface area.__
 * SOLID SHAPES.....

__**vocab
 * this is a 3-D shape**.

-isometric drawing.**__ is one in which the horizonttal lines of an obleject are represented by lines that form 30 degree angles, with a horizontal line in the picture.
 * -orthographic projection-** is a view in which an object in which the points of the object are projected, into a picture plain.


 * Spatial Relationships.....**
 * objectives...**

define dihedral angle.
 * define POLYHEDERON.
 * define the relationships among points, lines, segments, planes and angles, in three dementional space.


 * vocab....

- Polyhedron-** is a closed spatial figure composed of ploygons.
 * - Dihedreal Angle-** is a figure formed of two half planes with a common edge.
 * - Half Plane-** is a portion of a plane, that lies on one side, in a line, that includes the line.

objectives.**
 * Prisms.....


 * define, right prism, prism, and oblique prism.
 * examine the shapes of lateral faces of prisms
 * solve problems by using the diagnal measure of a right prism.

> d√( L2+W2+H2.)
 * vocab....**
 * **prism--** is a polyhederon that consists of a polygonal region and its translated image is passed onto a parallel plane with quadrilateral faces connecting corresponding angles.
 * the faces formed by the poloygonal region and its image is called a **BASE** of the prism.
 * the remaining faces, which are quadrilaterals are called, **lateral faces.**
 * a **right prisim** is a prism in which all of the lateral faces are rectangle.
 * a **oblique prism** is a prism that has at least one not rectangular lateral face.
 * a **diagonal** of a polyhederon is a segment whose endpoints are vertices of two different faces of the polyhedron.
 * diagonal of a right rectangular prism- in a right rectangular prism with dimensions lxwxh. the length of a diagonal is given by.

objectives...**
 * coordinates in 3-D.
 * identify the features of a 3-D coordinate system including the axis, octants, and coordinate planes.
 * solve problems by using the distance formula in 3-D.

vocab.... distance formula. d= √ ((x1-x2)2+(y1-y2)2(z1-z2)2))

objectives.** -identify and define the basic concepts of perspective drawing. -apply the basic concepts to create your own perspective drawings.
 * perspective drawing...

- vanishing point- its when two parall lines meet at a distance, in a drawing thats called a vanishing point. - in a perspective drawing, all lines taht are parallel to each other, but not to the picture plane, meet at a single point known as a vanishing point, 6.6.1. -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...
