Detailed Solution

For the statement
1st we have drawn the circle of chords equidistant from the center.
Given,
The perpendicular line OM = ON
The cord = AB and CD
1st step, we have verified the chord
AB = CD
2nd step, joined the line OC and OA
Now, we have
OMAB â12AB=AM
ONCDâ12CD=CN
Thus, we have considered the two triangles AOM and CON
Radius of the circle
OA=OC
As per given,
OM=ON
OMA=ONC=90
Question ImageTherefore, right hand side congruency we have
AOMCON
AM=CN â12AB=12CD̂AB=CD AB=CD
Hence The chords equidistant from the center of a circle are equal in length. this given statement is true.
Correct option is 1.
