BASIC GEOMETRY CONCEPTS AND DEFINITIONS:

Geometry: It´s the area of the movement.

Point: In the geometry, a point is defined  in two lines that are cut.

Line: Is a succession object formed of infinite points.

Ray: Is the line that starts at a particular point.

End Point: Is a point at wich a ray ends or satrst.

Midpoint: It´s the point that is halfway between the endpoints of the line segment.

Line Segment: It´s a line with two endpoints.

Straight Line: A line whose points follow the same direction.

Plane: Space limited by starights.

Lenght: Measurment of something from end to end.

GEOMETRY DRAWING AND SUPPLIES CONCEPTS AND DEFINITIONS:

Freehand: Draw by hand.

Line/Techincal Drawing: It´s a drawing made with tha help of supplies.

Compass: It´s a tool for drawings circles and arcs.

Protactor: An semicircular instrument, it sereves for measure of angles.

Set squares: It´s a material of draw.

Eraser: It´s use to erase.

Ruler: Is the instrument that serves to make lines.

Circle: set of  point at the same distance.

Circumference: full length of a circle.

Center: point equidistant of the points.

Radius: it is the length of a line segment.
Diameter: line segment that passes from the center.
Chord: line segment which conects two point.

Tangent: element to straight or curve lines.
Outer: when an element which doesn't touch a circumference.
Radius: it´s a line from the center and the perimeter
Diameter: line segment that goes from a point of the perimeter to another point, passing for the center of the circle
Chord: line that connects two points of the circle not through the center
Arc: segment of a circle
 Arrow:segment that divides an arc in the middle. It´s the center of the chord
Tangent: line that only touch a point of a circle
Inner: element inside the circumference
Concentric circles: circles with different radius but place in the plane sharing the center
