trigonometry - Determining Vector points on a circle -


i have problem trig , pre calc. given vector points oa (6 0) , vector ob (-6 0) , oc (5 root11) , points on circle radius of 6. how determine or show these points lie on circle?

for 3 points not mutually co-linear, there point equidistant each member of set. finding point given 3 arbitrary points (and not given radius) more informative project if you're learning trigonometry.

in example, solution simple: x2 + y2 = r2. each of points provided have values such sum of squares equals 36, expected circle of radius 6. problem easy because circle in question centered on origin.
