Lines That Intersect Circles Flashcards
1
Q
What is a Chord?
A
A segment whose endpoints lie on a Circle?
2
Q
What is a Secant?
A
A line that intersects a circle at two points.
3
Q
What is a Tangent of a Circle?
A
A line in the same plane as a circle that intersects it at exactly one point.
4
Q
What is the Point of Tangency?
A
The point where the Tangent and Circle intersect.
5
Q
What is a Radius?
A
A segment whose endpoints are the center of a Circle and a point on the Circle.
6
Q
What is the Circle Tangent Theorem?
A
If a line is Tangent to a Circle, then it is perpendicular to the radius drawn to the point of Tangency.
7
Q
What is the Circle Tangent Congruencey Theorem?
A
If two Segments are Tangent to a Circle from the same external point, then the Segments are Congruent.
