Explain the difference between a central angle and an inscribed angle?
A central angle has its vertex at the center of a circle, and two radii form the Arms. Central angle AOC is described as subtended by the chords AC and by the arc AC. An inscribed angle has its vertex on the circle, and two chords form the arms. Inscribed angle ABC is also described as subtended by the chord AC and by the arc AC.
How could you estimate the angle between two stars by the comparing that angle with your thumb or fist held at arms length?
Fist at arms length = ~ 10 arc degrees Thumb at arms length = ~ 2 arc degrees Little finger ~ 1 arc degree
What is the name of the corner where the two arms of an angle meet?
the orogin
What is the definition of an angle?
An angle is the shape formed by two rays, called the arms of the angle, meeting at a common endpoint, called its vertex.
What are two lines that have a common end point called?
They are the arms of an angle.
What are overlapping angles?
They are two angles where either one arm of each angle is between the two arms of the other angle, or both arms of one angle are between the arms of the other.
What is the angle between the star Aldebaran and the earth?
Between two points - like a star and Earth - you would have a line, not an angle. Angles may be indicated between two stars - that is, the angle would be star 1 - Earth - star 2.
The measure of an angle is the difference between the directions of its two?
arms or sides.

An inscribed angle has its vertex on the circle, and two chords form the arms. Inscribed angle ABC is also described as subtended by the chord AC and by the arc AC.
Is an angle formed when two rays are joined at their end points?
Yes, the definition of an angle is The amount of turn between two straight lines that have a common end point (the vertex). You can think of the arms as the two rays.
How could you estimate the angle between two stars by the comparing that angle with your thumb or fist held at arms length?
Fist at arms length = ~ 10 arc degrees Thumb at arms length = ~ 2 arc degrees Little finger ~ 1 arc degree
How is a reflex angle related to the other angle formed by the same arms?
They are related because you need the angle formed by the two arms in the formula for a reflex angle. The formula is:r=180+the angle made by the armsHoped this helped!
What is the name of the corner where the two arms of an angle meet?

What is an angle of separation?
"The angle of separation is the angle between lines originating from the eye of the observer toward two objects, such as a star-the Sun and the horizon." (quoted from Earth in space, a student guide and source book)
What is the definition of an angle?
An angle is the shape formed by two rays, called the arms of the angle, meeting at a common endpoint, called its vertex.
What are two lines that have a common end point called?
They are the arms of an angle.
Does extension decrease the angle between two bones?
No, extension usually increases the angle between two bones. When a joint is extended, it is straightened, which increases the angle between the two bones connected by the joint.
