        Outcomes for Lesson 1
  In this lesson we will:
  Discuss the features of Geometric Axiomatic System.
   Recap the terminology linked to circles.
   Investigate and prove that: Segment from centre of circle perpendicular
    to  chord bisects  chord.                                                         (Theorem 1)
   Investigate and prove that:  Segment from centre of a circle  to midpoint
     of chord is perpendicular to the chord.                                (Theorem 2)
   Investigate and prove that: Perpendicular bisector of chord passes
    through the centre of a circle.                                                (Theorem 3)
   Solve riders related to Theorems 1, 2 and 3.
