Yes, the hypotenus always goes through the middle of the circle.TomK wrote:QR_BBPOST Wait!...lol...if the lake is perfectly round and you start at the exact northwest corner and swim east for 30 meters then south for 40 you are tempting pythagoras but how does that make the 50 meter side go thru the center of the circle..does the hypotenus (sp) always go thru the center of a circumscribed circle on a right angled triangle?
That's actually how you make one with a compass. Start with the hypotenuse, find the middle, draw a circle around it. Then do the two sides...
But you do have me with the "exact north west corner" of a round lake.... I guess I needed to look a bit harder to find that corner....
