The tangent of the given circle should pass through one of the endpoints of the given chord of the circle. Only that angle should be considered which the chord is forming in the alternate segment. Solved Examples 1. Calculate the value of angles x and y in the given …
WebThe longest chord a circle can have passes through the center of the circle. Since this chord passes through the center of the circle and touches it on both sides, it is also a diameter. You know that a diameter is equal to two radii. Therefore, any length that is greater than 0 and less than or equal to the diameter would be a valid chord length.
