If two chords of a circle are equal, then their corresponding arcs are congruent and conversely, if two arcs are congruent, then their corresponding chords are equal.
Congruent arcs (or equal arcs) of a circle subtend equal angles at the centre.
9th class Theorem 9.7 Th 9.7 Class 9
The angle subtended by an arc at the centre is double the angle
subtended by it at any point on the remaining part of the circle.
9th class Theorem 9.8 Th 9.8 Class 9 converse of theorem 9.3
Angles in the same segment of a circle are equal.
9th class Theorem 9.9 Th 9.9 Class 9
If a line segment joining two points subtends equal angles at two
other points lying on the same side of the line containing the line segment, the four points lie on a circle (i.e. they are concyclic).
9th class Theorem 9.10 Th 9.10 Class 9
The sum of either pair of opposite angles of a cyclic quadrilateral
is 180º.
9th class Theorem 9.11 Th 9.11 Class 9 converse of theorem 9.10
If the sum of a pair of opposite angles of a quadrilateral is 180º,
the quadrilateral is cyclic.
