Multiple Choice

A tangent of a circle is ...

a line that has endpoints on the circle and passes through the centre of the circle.

a straight line that touches the circle at a single point.

a region of the circle bounded by two radii and an arc lying between the radii.

a line joining the centre of the circle to any point on the circumference circle.

Multiple Choice

In the diagram, a tangent and a line drawn to the point of tangency form a right triangle. Solve for "?" (the length of the hypotenuse)

-24

Multiple Choice

What can be concluded about the lengths of the tangents AP and BP drawn from point P to the circle?

AP is longer than BP

AP is shorter than BP

AP is equal to BP

AP and BP cannot be compared

Multiple Choice

What are the two segments created by a chord in a circle?

Major and Minor Segments

Upper and Lower Segments

Left and Right Segments

Inner and Outer Segments

Multiple Choice

What does the perpendicular line from the center of a circle to a chord do?

It bisects the chord

It extends beyond the chord

It creates a right angle

It forms a triangle

Multiple Choice

If two chords AB and CD are the same length then they will be the same perpendicular distance from the centre of the circle. What can be concluded about the distances OP and OQ?

OP > OQ

OP < OQ

OP = OQ

OP + OQ = AB
