An angle whose vertex is on the circumference of a circle and whose sides include chords of the circle is what kind of angle?
An inscribed 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.
What is an angle in a circle whose vertex is at the center of the circle?
Central Angle
What is an angle whose vertex is at the center of a circle?
A central angle.The section of the circle formed by that angle and the part of the circle (the part being the circumference) between the radii is called a sector.
An angle whose vertex is the center of the circle?
That is the central angle.
What do you call of an angle whose vertex is the center of the circle?
It is called a central angle.
Which angle has a tangent of 1?
The angle you seek is 45 degrees. The angle whose tangent is 1 can be written arctan(1) = 45 degrees.
What is an incribed angle in circle?
An inscribed angle is an angle whose vertex is on the circle and whose sides are chords.
What is the measure of an angle formed by a tangent and a secant drawn to a circle from an external point if it intercepts arcs whose measures are 70 and 30?
20 degrees
An angle whose vertex is in the center of a circle and whose sides intersect is called?
That's a "central angle", but the part that really fascinates me is this: What would it look like if you hadan angle whose vertex was in the center of the circle and whose sides didn't intersect ? ? ?
What is an angle whose vertex lies on the circle and whose sides are chords of the circle?
Inscribed angle
What is a circle whose center is located on the circumfrance of another circle?
A circle whose center is located on the circumference of another circle is called a tangent circle. The point where the two circles meet is called the point of tangency. In this case, the radius of the tangent circle is perpendicular to the radius of the original circle at the point of tangency.
An angle whose vertex is on the circumference of a circle and whose sides include chords of the circle is what kind of angle?
An inscribed angle.
An angle whose vertex is on the circumference of a circle and whose sides include chords of the circle?
it is arc angle
What do you call the angle whose vertex on the circle and whose sides contain chords of the circle?
It is an inscribed 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.
