5
parts of a circle 2 diameter chord chord chord diameter chord diameter
Which chords pass through the center? they are special chords
6
parts of a circle 3 Diameter, or just a chord? chord diameter
7
parts of a circle 4 semicircle arc Which arcs they are special arcs
are exactly half of the circle? they are special arcs
8
Semicircle, or just an arc?
parts of a circle 5 Semicircle, or just an arc? semicircle arc
9
parts of a circle 6 Which arcs are less than major arcs
half of the circle? major arcs minor arcs Which arcs are more than half?
10
parts of a circle 7 radius center major arc chord minor arc radius
11
parts of a circle 8 Major arc, or minor? minor major
12
parts of a circle 9 radius semicircle diameter semicircle radius
1 diameter = 2 radii 1 circle = 2 semicircles
