Mathematical system

• Underfined terms in geometry are terms which cannot be precisely defined and uses description
• Defined terms have a formal definition used to define more terms
• Axioms/Postulates statement which is accepted as true without proof used in proving some mathematical statement
• Theorems is a statement that can be proven it can be used in proving other statements
• Undefined terms- plane, point, line
• Defined terms- collinear points, coplanar point, subset of a line
• Axioms/Postulate- axioms, postulate
• Theorems -theorems
• Point a position in space it has only location but no dimension named using "Capital Letter"
• Line continues arrangement of infinitely points extends infinitely is opposite direction and is named by a single lower case letter or two points on a line
• Arrowheads symbolizes infinity
• Plane a flat surface that extends infinitely along it's length and width named by a single script capital letter or by three noncollinear points
• Collinear points are points that lie on the same line
• Non-collinear points are points that do not lie on the same line
• Coplanar points are points that lie in the same plane
• Non-coplanar points are points that do not lie in the same plane
• Line segment part of a line that consist two endpoints
• Ray part of a line with one endpoint and is extending in only one direction
• Opposite rays are rays with common endpoint but extending in opposite directions
