Geometry (from the Template:Lang-grc; geo- "earth", -metron "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer.


Points are considered fundamental objects in Euclidean geometry.

By Eucleur axiom, line can be drawn from 2 points . Example through 2 points A and B , we can draw a line AB


Example of lines[edit]


Lines of interest[edit]

Lines Definition Piture
Perpendicular lines Two lines intecsect at a point to form an angle 90o Perpendicular-coloured.svg
Parallell lines Two lines do not intecsect each other
Vector Line with its direction Vector from A to B.svg


Two lines intersect at a point to form an angle between 2 lines . Example Line AB intersects line AC to form an angle A between 2 lines . Angle has a symbol . Angle is measured in Degree(o) or Radian (Rad)

Example angle 90 degree is π radian
