Circles Arcs and Chords

In the diagram, TP and TQ are tangents to circle O. Determine the value of x. (Note the angles with single arcs are not necessarily congruent in this diagram.)

• 70

• 110

• 140

• 90

Find the value of x. 14 and 18 represent the entire length of the chords

• √512

• √32

• √35

• √128

In a circle (or congruent circles), chords that are the same distance from the center:

• are similar

• have the same name

• are congruent to each other

• are walking dead

Find PK.

Use chords to solve for x

• x = 35^o

• x = 50^o

• x = 70^o

• x = 140^o

Use chords to solve for x

• x = 3 cm

• x = 4 cm

• x = 5 cm

• x = 6 cm

In  a circle, if a radius or diameter is perpendicular to a chord, then it____ the chord and its arc.

• equals

• bisects

• arcs

• circles

In the diagram, the diameter of the circle is perpendicular to a chord. Solve for the value of "x" and "y"

• x=4, y=5

• x=3, y=7

• x=7, y=3

• x=6, y=9
