An angle that opens to the interior of the circle from a vertex on the circle?
This is the definition of an inscribed angle in geometry. An inscribed angle is formed by two chords in a circle that also share a common point called the vertex.
What is an arc formed by the endpoints of a inscribed angle?
They are two sections of the circumference of the circle.
What is the angle called that is formed by two radii with a vertex at the enter of a circle?
It is called the central angle. Hope that helped!
What are the dimensionof angle?
Angle is dimensionless. It's actually the ratio of two lengths ... the length of an arc of the circle to the length of the radius of the circle. That ratio is the same number for the same angle in any-size circle, and it's directly proportional to the angle that cuts the arc. When you measure angles in radians, the angle IS that number.
What is the chord of a 7m radius?
The angle at the circle centre is required. Draw a line from each end of the chord to the circle centre. Draw a line from the centre of the chord to the centre of the circle creating two right angle triangles, the hypotenuse of both = the radius (7 metres). Then > Length of chord = ((Sine ( centre angle / 2 ))* 7) * 2
What is an arc central angle and radius of the circle?
Radius: A line from the center of a circle to a point on the circle. Central Angle: The angle subtended at the center of a circle by two given points on the circle.
An inscribed angle is formed by two radii?
false
What is an angle formed by two radii of a circle called?
central angle central angle
What is the measure of the angle formed by two tangents drawn to a circle from an external point if they intersect a major arc whose measure is 230?
-- The major arc = 230 degrees-- The minor arc ... the arc between the tangents ... is (360 - 230) = 130 degrees.-- The line from the vertex of the angle to the center of the circle bisects the arc,so the angle between that line and the radius to each tangent is 65 degrees.-- The radius to each tangent is perpendicular to the tangent. So the radius, the tangent,and the line from the vertex to the center of the circle is a right triangle.-- In the right triangle, there's 90 degrees where the radius meets the tangent, and65 degrees at the center of the circle. That leaves 25 degrees for the angle at thevertex.-- With another 25 degrees for the right triangle formed by the other tangent,the total angle formed by the two tangents is 50 degrees.
An angle that opens to the interior of the circle from a vertex on the circle?

Is an angle formed by two rays whose vertex is the center of a circle?
Yes
What is an arc formed by the endpoints of a inscribed angle?
They are two sections of the circumference of the circle.
If you only have the central angle of a circle can you find the radius?
If "the angle" means the angle between two radii at the centre, the answer is no. You need to know the circumference first. Then use radius = circumference divided by 2 x pi.
What is the angle called that is formed by two radii with a vertex at the enter of a circle?
It is called the central angle. Hope that helped!
What do you call a quarter of a circle?
A quarter of a circle, formed by two radii forming a right angle at the centre, is called a quadrant.
