Lecture on Circles; Inscribed Angle and Arc

Find the measure of arc AB.

• 17 degrees

• 34 degrees

• 68 degrees

• 146 degrees

inscribed angle: an angle with its vertex _____________ the circle

• at the center of
• on

Solve for x

• 51 degrees

• 61 degrees

• 102 degrees

• 204 degrees

What is x?

• 15

• 23

• 2

• 92

Find m∠PRQ.

• 39°
• 90°

• 15°

In a circle (or congruent circles), congruent arcs:

• have congruent chords
• have congruent points
• are twice the measure of their radii
• can climb a hippo

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

Solve for the missing angle.

• 45^o
• 90^o
• 22.5^o
• 128^o

Find a and b.

• a=74 degrees
  b=93 degrees
• a=93 degrees
  b=74 degrees
• a=87 degrees
  b=106 degrees
• a=106 degrees
  b=87 degrees
