Circle Basics
What line segment spans from one side of a circle to another but does not go through the middle?
chord
This is an angle created within the circle containing two chords.
Interior angle
What gives you the measurement around the circle. It is like perimeter.
circumference.
What is the measure of an interior angle when the intercepted arcs measure 98 and 22 degrees respectively?
60 degrees
If the central angle is 72 degrees, what is the measure of the inscribed angle sharing the same intercepted arc?
36 degrees
What line segment starts at the center and goes to the edge of the circle?
radius.
What is the measure of the angle created by two secant lines intersecting outside the circle with intercepted arcs measuring 135 and 85 degrees respectively?
25 degrees
If the inscribed angle is 38 degrees, what is the measure of its intercepted arc?
76 degrees
What line segment is double the radius?
diameter
What is the measure of two secant line intersecting outside the circle and the two intercepted arcs measure 135 and 45 degrees?
45 degrees
If a chord and a tangent line intersect, it creates and angle with a measure of 27 degrees, what is the measure of its intercepted arc?
54 degrees
What point gives a circle its name?
center
If two tangent lines intersect outside the circle, and the angle they creates measures 50 degrees, what are the two measures of the intercepted arc?
205 and 155 degrees
See figure on the board:
What is the measure of x?
140 degrees
