Problem Set, starts on page 41
Complete 1, 2, 3, 4, and 5.
Explain all your thinking. Write neatly
and in an organized way.
Use the diagram to help you identify the following
terms:
Arc
Minor and major arc
inscribed angle
central angle
intercepted arc of an angle
Use the diagram to help you identify the following
terms:
Arc
An arc is a portion of the circumference
of a circle
Use the diagram to help you identify the following
terms:
Minor and major arc
BE is a minor arc
EDB is a major arc
What’s the difference?
Use the diagram to help you identify the following
terms:
inscribed angle
Angle BDC is an inscribed angle
angle whose vertex is on the circle, and
each side of the angle intersects the
circle in another point.
Use the diagram to help you identify the following
terms:
Central angle
angle BAC is a central angle
An angle whose vertex is the center of
the circle.
Use the diagram to help you identify the following
terms:
intercepted arc of an angle
angle CDB and angle CAB both intercept
arc BC . What do you think it means for
an angle to intercept an arc?
Use the diagram to help you identify the following
terms:
intercepted arc of an angle
An angle intercepts an arc if the
endpoints of the arc lie on the angle, all
other points of the arc are in the interior
of the angle, and each side of the angle
contains an endpoint of the arc.
