Theorem statement

• Line perpendicular to chord

• Perpendicular bisector of chord

• Line from centre perpendicular to chord

• Line thru centre and midpoint

Theorem Statement:

• Angle at centre = 2x angle at circumference

• Angle at centre = 2x angle at arc

• Angle at centre = angle at circumference

• Angle at centre = angle at arc
