     POINT : Is a place that two lines intersec . The point hasn't got a :dimension , height and width . 

    

     LINE : It's a dimension that never finish . Because  hasn't got points . 

      RAY : It's an object that go to point to point . It got an start and a finish . 

      MINDPOINT : Is a line segment . 

      LINE SEGMENT : It's a line wiht two endpoint . 

     ENDPOINT : Aline that start and end .

     LENGHT : Measurement  of something  from end to end .

                   GEOMETRIC DRAWING AND SUPPLES COCEPTS AND DEFINITIONS 

       FREEHAND : Drawing with out intruments only with your hand .

      COMPASS : It's an instrument that we use for  do circules and arcs .  Also for measuring distance 

        

         between  two points . 

  

     PROTACTOR :  It's an instrument  for measuring drawing angles on a paper usualy flat 

      semicircular transparent plastic  sheet  graduated . 

    SET SQUARE :  There are two special rulers with a triangular  shapes  . One is called the 45º and 

     the other called the triangle 60º / 30º.  

     ERASER : We use for limitade lines . 

    RULER : Element to do perfect lines . 

   
          IMPORTANT DEFINITIONS ABOUT CIRCLES

CIRCLE : Is a curve line to adistance to a point called center .
 CIRCUNFERENCE: Is a full circle. 
CENTER : Is a point equidistant to any points on a circle . 
RADIUS : A length of a line segment from the center to its perimeter . 
DIAMETER: Is a line segment . Is the double than the radius but  the diameter it has to past to the center. 
CHORD : A line segment wich conects two points of the circle but don't past to the center is perpendicular . 
ARC  : Segment of a circle . 
ARROW: It's a line segment enter chord and arc pass to the center .  

      

  

  IMPORTANT DEFINITIONS ABOUT ANGLES AND LINES 

PARALLES :There are two lines which never intersect thenselves so all their points are eaquidistant .
PERPENDICULAR:They are two lines that intersect in a point and made 4 angles of 90º.
OBLIQUE: Two lines which aren't parallels and perpendiculars.
ANGLES:It's a figure formade of two lines , intersect in a point. 
  
TYPES ANGLES
Complementary angle: There are two angles that form a 90º angle
Splementary angle: There are two angles that form a 180º angle.
