expressions
e.g. If x =60 and y = 20, find
C.
C = 4(60) + 3(20) = 300

many-to-one, many-to-many.
Functions as a mapping,
determination of the rule of a
given mapping/function.

Chord

Chords.

(ii) The angle which an arc of a
circle subtends at the centre
of the circle is twice that
which it subtends at any
point on the remaining part
of the circumference.

– Angles subtended by chords
in a circle and at the centre.
Perpendicular bisectors of
chords.

(iii) Any angle subtended at the
circumference by a diameter
is a right angle.

– the formal proofs of those
underlined may be required.

) Angles in the same segment
are equal.
(v) Angles in opposite segments
are supplementary.

circle and from the point of
contact a chord is drawn,
each angle which this chord
makes with the tangent is

used.

Chord property

1v. Angles in the same segments are equal

V. Angles in opposite segments are supplementary

Vi. Perpendicularity of tangent and radius
