Which of the following can be a perimeter t of a triangle inscribed in a circle of radius 1?
I. 0.001
II. 0.010
III. 0.100  Choose one:
A) I only B) III only C) II and III only D) I, II, and III E) Not I, II, or III
Yes,the length of any side of a triangle must be larger than the positive difference of the other two sides, but smaller than the sum of the other two sides.   But how do you use the above property to solve the question?   The lower limit of the perimeter of an inscribed triangle in a circle of ANY radius is 0: t&gt;0.   Answer is I, II, and III.
