1. 6 Circles (Part 1) 1. Circle Notes A circle is the set of all points in a plane at a given distance from a given point.

2
1. Circle Notes Draw and define. A semicircle is an arc of a circle whose endpoints are the endpoints of a diameter.

3
1. Circle Notes C The given distance is called the radius and the given point is called the center.

4
**The given distance is called the diameter and the point is the center.**

1. Circle Notes C The given distance is called the diameter and the point is the center.

5
1. Circle Notes Diameter is the longest cord A chord of a circle is a geometric line segment whose endpoints both lie on the circumference of the circle.

6
**Tangent is a line which touches a circle at just one point.**

1. Circle Notes tangent Tangent is a line which touches a circle at just one point.

7
1. Circle Notes Secant Cord is portion of a secant A secant line is a line that (locally) intersects the circle in two points. Cord is portion of a secant

8
1. Circle Notes Discuss different ways to write major and minor arcs. Note: we did a LOT of discussion here. I put up letters over every intersection and asked them to name the arcs, point to them, etc.

9
1. Circle Notes An arc of a circle is two points on the circle and a continuous (unbroken) part of the circle between the two points. An arc of a circle is two points on the circle and a continuous (unbroken) part of the circle between the two points.

1. Classwork Can a chord of a circle also be its diameter? Can it be a tangent? Why or why not? Can two circles be tangent to the same line at a point? Draw a sketch and explain.
