Theorem 10.5 : There is one and only one circle passing through three given non-collinear points.
Text Solution
Verified by Experts
In `/_\OPM` and `/_\OQM`
`OM=OM` (common)
`/_OMP=/_OMQ` (Perpendicular angles)
`PM=QM`
By SAS congruency, `/_\OPM` and `/_\OQM` are congruent.
`OP=OQ`
Similarly, we can prove that,
...
