Given a circle having two chords of equal length. The angle subtended by one of the chords to the centre is given. The task here is to find the measure of the angle subtended by another chord at the centre.
Input: 48 Output: 48 degrees Input: 82 Output: 82 degrees
Let AC & BD are the two equal chords of the circle having center at O.let the angle subtended by the chord AC be x degrees.
in triangle AOC & BOD,
AO = OB(radii of same circle)
AB = CD(equal chords)
OC = OD(radii of same circle)
so, the triangles AOC & BOD are congruent to each other
so, angle AOC = angle BOD
Equal chords of a circle subtend equal angles at the centre.
Below is the implementation of the above approach:
The angle subtended at the center is 48 degrees
- Program to calculate angle on circumference subtended by the chord when the central angle subtended by the chord is given
- Angle subtended by the chord to center of the circle when the angle subtended by the another equal chord of a congruent circle is given
- Length of the chord of the circle whose radius and the angle subtended at the center by the chord is given
- Angle between a chord and a tangent when angle in the alternate segment is given
- Length of the chord the circle if length of the another chord which is equally inclined through the diameter is given
- Distance of chord from center when distance between center and another equal length chord is given
- Exterior angle of a cyclic quadrilateral when the opposite interior angle is given
- Distance between centers of two intersecting circles if the radii and common chord length is given
