BASIC GEOMETRY CONOPTS AND DEINITIONS
Geometry: It´s and of Know Lenge wich studies any elements and operations on/in the plane such aspoinis, lines or shapes. It comes from the Greek, geo < eah and metry = meassurement.
Point: In geometry a point can be defined as the place or lation where two lineas inters. A point his not dimensions, no heigh and no widh.
Line: A one- dimensional object formed of infinite points. It hat hot end points and continues on forever in / a plane
Ray: A line wich lengis at a particular pant ( called the endpoind ) and extends endlessy in one direction.
Mydpoint: It is point that is halfwas between the endpoints of the line segment.
End- point: And end Point is a point at which a line segment or a ray ends or starts.
Line Segment: It is a line with two endpoints.
Length: Mesurement of something from end to end.
GEOMETRY DRANING AND SUPPLIES CONCEPT AND DEFINITION
Freehand: Draw buy hand without guiding instruments meusments...
Line / Techical drawing: It is a drawing made with the help of suppliies. It is usually the kind of drawing used for arehi teotare or engring plans.
Compass: It is a tool for drawing circle and also for measuring distance between points, comisting in two arm linked buy a hinco.
Protactor: Am instrument for measuring or drawing angle on paper, usually a flat semicircular transparent plastic sheet gracluted in degress.
Set Squares ( UK) Triangles ( US): They are two special rulers with triangularshape. One is called the 45º triangle and other 60º/30º triangle . Both have 90º angle: They are used for makin diferent angles.
45º triangle 60º/30º triangles
Ureser: Use for eliminate themistake
Ruler: For making lines.
Line Segment coying: Given the segment AB, copy it with the same leght with a compass.
Addition: Sumar.
Subtaction: Restar
Multiply: Multiplicar
Division: Perpendicular segment line bisector ( mediatriz )
Repeat the exercise:
Perpendicular: Line of a segment through an end point.
