An inscribed angle is an angle formed by two chords that share an endpoint.?
An inscribed angle is formed by two chords in a circle that meet at a common endpoint on the circle's circumference. The vertex of the angle lies on the circle, and the sides of the angle are segments of the chords. The measure of an inscribed angle is half the measure of the arc that it intercepts. This property is a key characteristic of inscribed angles in circle geometry.
What is the measure of angle abc in a circle 134 degrees?
In a circle, the measure of an angle formed by two chords that intersect at a point inside the circle is equal to the average of the measures of the arcs intercepted by the angle. If angle ABC measures 134 degrees, it means that the angle is formed by the intersection of two chords, and the measure of the arcs it intercepts will average to this angle. Thus, angle ABC is 134 degrees.
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 a sector in a circle?
A sector in a circle is a portion of the circle defined by two radii and the arc that lies between them. It resembles a "slice" of the circle and is often described in terms of its central angle, which is the angle formed by the two radii. The area of a sector can be calculated using the formula ( A = \frac{\theta}{360} \times \pi r^2 ), where ( \theta ) is the central angle in degrees and ( r ) is the radius of the circle. Sectors are commonly used in geometry and various applications, such as in pie charts.
What is an arc formed by the endpoints of a inscribed angle?
They are two sections of the circumference of the circle.
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.

What is an angle formed by two radii of a circle called?

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.

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!
