Postulates (Mathematical system)

• Are statements which need to be proven

  Theorems
• Are direct consequences of theorems

  Corollaries
• Is a figure which has no length, width or thickness.

  Point
• Is a part of a line that includes an endpoint and all points to a specific direction

  Ray
• A ray without the end point

  Half-line
• A part of a line between two points and including the end points

  Segment
• Is the point on a line segment that divides the segment into two congruent segments

  Midpoint
• What does a point generate when it moves in any direction?

  line
• What does a line generate when it moves?

  A plane
• Are angles whose measure has a sum of 90

  Complementary angles
• are angles whose measure have a sum of 180

  Supplementary angles
• Two lines are congruent if they have the same measure
• Two angles are congruent if they have the same measure
• It consists of any set of axioms used to derive a theorem

  Axiomatic system
• are lines that form angles whose measures are 90

  Perpendicular lines
