NICE TO MEET YOU!
Thank you for coming today!

Solid shapes such as cubes, cuboids, pyramids, etc all onsist of points, lines, and
planes, which are the principal elements of space.

Opening

Point
A point is drawn (shown) by means of a dot and is
labeled with a capital letter, for example: point A, point B, point C,
point P, point Q, etc.

Line
A line is a set (collection) of points. A line
has an infinite length, or does not have any limit to
either side (right and left), and so we only draw a
segment of it as its representation. A line is labeled
with a lower case letter, such as line g, line h, line k,
line l,etc.
Understanding lines according to Graphic
Lexicon (researchers) is a thin two-dimensional
object lengthwise. While Lillian Gareth (researcher)
defines the line as a set of points that when dragged
then the dimension of its length will look prominent
and the figure is called the line.
So it can be concluded that the line is a collection of
dots that are infinitely numerous, with the distance
between the points very close.
The formation of lines is the movement of a
point that traces the trace so as to form a scratch. To
cause scars, use pencils, pens, brushes and others.
For the art of line has a fundamental function, so it is
likened to the heart of fine arts. Lines are often called
contours, a word that is vague and rarely used.
ABOUT LINES
Kinds of Line

Cross line
Line parallel
Types of Lines Parallel Lines Two lines are said to be
1 parallel when the two lines are located on a single plane
that will not intersect even if it is extended indefinitely.
4 Crossed lines Two lines are said to cross, if they are
not parallel and do not intersect.

Lines squared Horizontal line

Lines squeeze Two lines on a plane are said to Horizontal line A line is said to be a horizontal line if the
2 coincide if and only if they have at least two cut points
(two points of partnership).
5 line is horizontal. The horizontal sense is the horizon
parallel (the lower sky that borders the earth according to
the eye view),

Line Intersect Vertikel line

3 Intersecting Lines Two lines on a plane are said to


intersect if and only if they have a common point.
6 The vertical line of the vertical line is a line
perpendicular to the horizontal line
.
Straight line
Straight line It is said straight line if the ends A and B are perpendicularly straight unlimited
7 then the line is called a straight line AB and is written AB

Curve line
8 The curved line Line connecting two points and points in a straight

Example Line Parallel

Swimming Pool

You can pay attention to the pool.


You can see the ropes for every swimmer.
The ropes never intersect. In this case the
rope barrier is said to be parallel.


Clock

You can pay attention to


the wall clock. At 12.00 hours, a
long needle coincides with a short
needle (clockwise needle), or lies
on a line.
Book

Looked your note math


textbook or notebook. Suppose your
book is rectangular. Both borders on
the book intersect at one point. The
two boundaries are intersected at one
point. The two boundaries of
intersection are shown as two
intersecting lines.
Bridge

Looked the bridge over


the river. In this case the bridge
will never cut the river. Bridges
and rivers are not parallel
because they do not lie in one
area. The position of the bridge
and the river can be regarded as
a crossed line.
Cuboids
