Page 450
1.
The angle inscribed in a semicircle
is always _______________
O
2.
Inscribed angles subtended by the same
arc of a circle are _____________
O
Minor Arc
Major Arc
Note: this last property can be described using chords instead of arcs (as shown below) but it is
a little trickier because for a given chord, there is both a major and minor arc associated with it
Inscribed angles subtended by the same
chord are equal when the angles are on the
___________________ of the chord.
When the angles are on _____________
sides of the of the chord then the angles
are ________________________
(note: one angle inscribes the minor arc
and one inscribes the major arc)
O
3.
The central angle is ____________ the
measure (i.e. value, size) of the
inscribed angle subtended by the same arc.
O
Minor Arc
Major Arc
O
