BASIC CONCEPTS OF GEOMETRY:
Geometry: It is an area of knowledge which studies any elements and operations on/in the plane such as points, line sor shapes. It comes from the Greek geo "earh", metry "measurement".
Point: In geometry a point can be defined as the place or location where two lines intersect. A point has no dimensions, no heigh and no width.
Line: a one-dimensional object formed of infinite points. It has no end points and continues on forever in a plane.
Plane: It is a two-dimensional (height and width) surface. In the space plane can be defined by two parallel lines, two intersecting line sor one point and a stright line.
Segment: A portion of a stright line defined by two points.
Straight Line: A line traced by a point travelling in a constant direction.
Perpendicular segment bisector: A line that intersects or meets a segment through its midpoint in equal parts forming 90º angles.
Angle bisector: A straight line though the vertex of an angle which divides it in two equal angles.
Thales theorem: Two lines intersected by a set of parallel lines get divided in proportional portions. This theorem is used mainly to divide segments in equal parts.
Axis: A straight line that express a symmetry a height or width regarding a figure or geometric set of elements.
Perimeter: The path that surrounds a two-dimensional shape also referred as the boundaries.
Perpendicular: They are lines which meet forming four right angles.
Parallel: They are lines which never intersect theirselves, so all their points are equidistant.
POLYGONS:
Polygon: A polygon is a flat and closet shape formed by straight sides joined by vértices.
Side: A segment which belong to a polygon.
Vertex: A point in which two sides of a polygon converge.
Diagonal: The line segment connecting two nonadjacent vértices in a polygon.
Star polygon: They are the result of connecting non consecutive vértices of a polygon.
Pentagram: A star polygon.
Hexagram: A star hexagon.
Triangle: A three sided polygon.
Quadrilateral: A four sides polygon.
Square: A four equal sides polygon with two couple of equal vertices.
Rhombus: A four equal sides polygon with two couple vertices.
Hexagon: A six sides polygon.
Heptagon: A seven sides polygon.
Octagon: An eight sides polygon.
Enneagon: A nine sides polygon.
CIRCLE:
Circle: A set of points equally distant to a point called center.
Center: A point which is equally distant from any point of a circle or from any vertex of a regular polygon.
Circumference: The distance around the outside of a circle, that is to say, the circle's perimeter.
Radius: Distance between the center and any of the points of the circumference.
Diameter: A line through the center of a circle which conects two points of it.
Chord: Segment which joins two circle points no through its center.
Arc: A portion of a circle.
