Paper 2

Clarification

• Assessment standards from Grade 10 will be assumed knowledge.
• The concept of collinearity must be understood.
• Prove properties of polygons using analytical methods.
  For example:
  Prove that the quadrilateral:
  A(–1 ; –2),
  B(–4 ; 2),
  C(1 ; 2) and
  D(4 ; –2)
  is a rhombus.

Use a two-dimensional Cartesian co-ordinate system to derive and apply:
(a) the equation of a circle (any centre);
(b) the equation of a tangent to a circle given a point on the circle.

Clarification

• All assessment standards from Grade 10 and 11 will be assumed knowledge.
• Learners are expected to know and be able to use as an axiom:
  "The tangent to a circle is perpendicular to the radius drawn to the point of contact."
• Concepts such as:
  - Inscribed-centre
  - Circumscribed
  - Incentre
  - Orthocentre
  - Centroid
  will not be examined.
