Which rules describes the picture? 
Inscribed Angles
-
What are the two rules and properties of inscribed angles?
- The measure of an inscribed angle is 1/2 of its intercepted arc
- If two inscribed angles of a circle intercept the same arc, then the angles are congruent.
-
What rule describes this picture?
Inscribed polygons
-
What are two the rules and properties of inscribed polygons?
- If a right triangle is inscribed inside of a circle, then the hypothnuse is the diameter.
- A quadralateral can be inscribed if and only if opposite angles are supplementary.
-
What is the rule for Chords and Congruency?
Two minor arcs congruent if there corresponding chords are congruent.
-
What is the rule for Chords and the Center?
Two chords are congruent if they are equal distances from the center.
-
What are the two rules for Chords and Perpendicular Bisectors?
- If a chord is the perpendicular bisector of another, then the first chord is a diameter.
- Also, the diameter, if perpendicular to a chord, bisects the chord and its arc.
-
What are the two rules of tangents?
- A line is tangent to a circle if and only if the line is perpendicular to the end of a radius of a circle.
- Tangent segments from a common external point are congruent.
-
What are the three are measure rules?
- minors arcs measure less than 180 degrees.
- major arcs measure between 180 and 360 degrees (not including 180 degree semi circle.
- the measure of an arc is the measure of its central angle.
