Prove that the circle drawn with any side of a rhombus as a diameter, passes through the point of intersection of its diagonals.

Text Solution

Verified by Experts

`ABCD` is a rhombus. Circle is drawn taking side `CD` diameter. Let the diagonals `AC` and `BD` intersect at `O`.
Angle in the semicircle and diagonals of rhombus bisect at right angles at `O`.
`/_DOC=90`
. `/_DOC=/_COB=/_BOD=/_AOD=90`
Circle passes the point of intersection of its diagonal through `O`.
