Exterior Angles
Angles- 20
arcs- 130 and 75
135-20=115
115 divided by 2 = 57.5
the inscribed angle
what is angle always half of the arc
circle with a
angle sector- 60
arc-65
Find the angle for arc x
x = 55
Angles 40,90,140
90+90=180
90+y=180
which is not a central angle?
circle with it's angle not in the midpoint of a circle
angle = x
angle = 132
228
228-132 divided by 2 = x = 48
the arc measurement
what is equal to the central angle that forms the intercepted arc
circle with 2 sectors
48 & 215
find the outer angle for arc 215
392=x
Angles-
113
midpoint-4
angles-D,E,F,G
2(133)
266=arc
worth 2 and 66
outer arc angle 25 and 2
89
exterior angle = 4
external angle = x
arc 130
80=130- x
x=50
The diameter in a circle
What is the chord passing through the center of a circle
circle with
arc angle - 10
arc 15
find the angle for A
5 = x
Angles D Q R
inner angle- S
180=90
180-90=90
circle with
sectors - 3 (and arc 30) and 10
Angle A
Outer arc B
140
exterior angle= x
interior angle = 30
arc=90
exterior angle measurement = 120
240
90-30 divided by 2 = 60 divided by 2
=30
The chord
What is the straight line segment whose endpoint lie on the edge of a circle
circle with 2 sectors
B and ?
outer angle for B is 40
arc with 280
160
Angles- W,X,Y,Z
Arc 62
angle 31
2 x angles=arc
=31
circle with
sectors - 1(arc 10) and 99(arc D)
arc worth 2
71
exterior angle x
interior angle 40
arc 80
80-40=40
40 divided by 2 = 20
The major Arc
What is the arc with a measurement greater than 180 degrees
circle with
sector angle - 2x-9

opposite side is 89
44.75
Angles- A,D,B,C
arc - 94
angle-47
180=94
=86
Circle with
2 sectors - 10(arc 5 ) and 20(arc D)
