What angle has the same measure as its arc?
Central angle
Is the measure of an arc congruent to the measure of its central angle?
No.
What is a central angle and what is the relationship of the central angle and the intercepted arc?
In a circle, a central angle is formed by two radii. By definition, the measure of the intercepted arc is equal to the central angle.
If a central angle measures 87 and deg then its arc will measure .?
The same as the central angle of the circle
How do you find the radius when the arc length IS GIVEN?
You also need the measure of the central angle because arc length/2pi*r=measure of central angle/360.
How do you find the measure of the central angle?
the measure of the inscribed angle is______ its corresponding central angle
What angle has the same measure as its arc?
Central angle
Is the measure of an arc congruent to the measure of its central angle?
No.
What is a central angle and what is the relationship of the central angle and the intercepted arc?
In a circle, a central angle is formed by two radii. By definition, the measure of the intercepted arc is equal to the central angle.
How does the central angle compare to the inscribed angle if it is on the same side of a common chord?
The central angle is double the measure.
Do octagons have obtuse angles?
Yes. It must have an obtuse angle.
If a central angle measures 87 and deg then its arc will measure .?
The same as the central angle of the circle
What is the measure of the central angle of a decagon?
30
What is the measure of each central angle of a quadrilateral?
That depends on the quadrilateral. They will not all have the same measure. Even rectangles will not all have the same central angle measures.
Is the measure of a minor arc equal to the measure of its central angle?
CONGRUENT
If the measure of a minor arc is 155 what is the measure of its central angle?
155
What is the measure of a central angle for a regular polygon?
Each central angle is (360) divided by (number of sides in the polygon).
