UNIT # 3 BASIC GEOMETRY

LEARNING OBJECTIVE

Students able to draw a picture on graph paper and plot the coordinates then generated to computer image using microsoft excel.

Geometry, which literally means 'Earth Measure", is the study of space and the shapes within it. Geometry is necessary for us to understand the objects in our world, and we study it by considering its dimensions, which are as follows:

- 0 dimensions (0D) : A point or position. It has no size. For example, a point on a map indicates a position but doesn't have a size or shape.
- 1 dimensions (1D) : Linear/Line. It has length only, such as the top edge of this page or a number line.
- 2 dimensions (2D) : Plane region. It has both length and width (area), such as this page or the top of a DVD
- 3 dimensions (3D) : Space region. It has length, width and heigh (volume) such as a book or a drink can.

**COORDINATES (CARTESIAN COORDINATES)**

These are pairs of numbers or symbols that represent a position in a plane. The first number in the pair indicates the distance of a point along the horizontal x - axis, and the second number indicates the distance of the point along the vertical y - axis.

In
the four quadrant format, both the x - and y - axes have positive and
negative numbers. Remember that the first digit in each pair represents
how far along the x-axis the point sits, and the second digit represents
how far up or down the y - axis it sits.

Note the position of the points according to whether they are positive or negative numbers.
