1. Solve problems and justify
the solution strategy using
circle properties, including:
• the perpendicular from the
centre of a circle to a
chord bisects the chord
• the measure of the central
angle is equal to twice the
measure of the inscribed
angle subtended by the
same arc
• the inscribed angles
subtended by the same arc
are congruent
• a tangent to a circle is
perpendicular to the radius
at the point of tangency.
