**Week 1:**LOGICAL REASONING

i. Simple and compound
statements

ii. Logical operation and
truth tables

iii. Conditional
statements and indirect proofs.

**Week 2:**LINEAR INEQUALITIES

i. Linear inequalities in
one variable

ii. Linear inequalities
in two variables

iii. Range of values of
combined inequalities

iv. Graph of linear
inequalities in two variables

v. Maximum and minimum
values of simultaneous linear inequalities and application of linear
inequalities in real life situation

**Week 3:**CHORD PROPERTIES

i. Angles suspended by a
chord in a circle

ii. Angles subtended by
chord at the centre

iii. Perpendicular
bisectors of chords

iv. Angles in alternate
segment

v. Cyclic quadrilaterals

**Week 4:**CIRCULAR THEOREMS

i. Proof of the theorem:
The angle which an arc suspends at centre is twice the angle subtended at the
circumference

ii. Proof of the theorem:
The angles in same segment are equal

iii. Proof of the
theorem: The angles in a semicircle is one right angle

iv. Proof of theorem: The
opposite angles of cyclic quadrilateral are supplementary

v. Proof of the theorem:
The tangent to a circle is perpendicular to the radius

**Week 5:**CALCULATION ON CIRCLE THEOREM

i. Angle at centre is
twice angle at the circumference of circle

ii. Angles in the same
segment are equal

iii. Angle in a
semicircle is 90°

iv. Opposite angles of a
cyclic quadrilateral are supplementary (i.e. when the opposite angles are
added, they give 180°)

v. Tangent to a circle
(i.e. Radius of a circle is perpendicular to the tangent of a circle)

**Week 6:**TRIGONOMETRY 1

i. Derivation of sine
rule and its application

ii. Derivation of cosine
rule and its application

**Week 7:**THE RIGHT-ANGLE TRIANGLE

i. Angles of elevation
and depression

**Week 8:**BEARING

i. Definition and drawing
of 4 cardinal, 8 cardinal points and 16 cardinal points

ii. Notation for bearings
cardinal notations N30°E, 545°N, 3 digits notations e.g. 075°, 350° etc.

iii. Making sketches
involving lengths and angles/bearing

iv. Problem solving on
lengths, angles and bearings

**Week 9:**PROBABILITY

i. Throwing of dice, tossing
of coin and pack of playing cards

ii. Theoretical and
experimental probability

iii. Mutually exclusive
events

**Week 10:**PROBABILITY II

i. Independent events

ii. Complementary events

iii. Outcome tables

iv. Tree
diagram/practical application of probabilities in health, business and
population
