**for Knights**

Just a final note. Since the 3rd altitude h is bounded by 1/a + 1/b <= 1/h <= 1/a - 1/b where a < b, the limiting case where a=b (an isosceles triangle) shows that 1/a+1/a <= 1/h <= 1/a - 1/a 2/a <= 1/h <= 0 shows that h >= a/2, and may grow without bound.

**for Knights**

In a right triangle, if the legs (altitudes are 12 and 14), then if we pick an angle θ and let h be the altitude to the hypotenuse, h/14 = sinθ h/12 = cosθ so h^2/144 + h^2/196 = 1, and h =~ 9.1 So, Reiny's estimate is way low. Now the question is, does a ...

The error is in your third line you take 1/2 of the middle coefficient, and then square it (1/2)(1/2) = 1/4 --- (1/4)^2 = 1/16 3rd line: b^2 + (1/2)b + 1/16 = 3 + 1/16 (b+1/4)^2 = 49/16 b + 1/4 = ± 7/4 b = -1/4 ± 7/4 = 6/4 or -8/4 b = -2 or 3/2 since we have ...
