Geometry/ Circle Geometry HSG.C.A.2
Identify and describe relationships among inscribed angles, radii, and
chords.
Definitions
____________ - A segment whose endpoints are the center of the circle and a point on the circle.
___________- A segment whose endpoints are on the circle.
______________- A chord that contains the center
_____________ - A line that just touches a curve at one point, without cutting across it.
_________ ______ - Circles with congruent radii
__________ ______ - Circles that lie in the same plane and have the same center
What is the Relationship Between Angles in Circle Geometry?
_________ _____ - An angle whose vertex is on the circle and whose sides are chords of the circle
_______ _____ - A central angle is the angle that forms when two radii meet at the center of a
circle.
___________ _____ - An angle whose rays are tangent to the circle
How Does a Complete Proof Read?
Proving that the angle subtended at the circumference by a semicircle is a right angle.
