Can you confidently solve more than 5 problems and justify your strategies using the circle properties below?

The perpendicular from the center of a circle to a chord bisects the chord

Example: Draw a radius that intersects a chord and prove the chord is bisected.

The central angle is equal to twice the inscribed angle subtended by the same arc

Example: Given a central and inscribed angle from the same arc, calculate the missing one.

Inscribed angles subtended by the same arc are congruent

Example: Show that angle ABC and angle ADC subtended by the same arc AC are equal.

A tangent to a circle is perpendicular to the radius at the point of tangency

Example: Given a tangent and radius, prove they meet at a right angle.

Can solve problems using one or more circle properties

Example: Use a combination of circle rules to solve for unknown angles or segment lengths in a complex diagram.
