Answer to Problem 7GRFC
The conjecture
Explanation of Solution
Given:
The given collinear points is
Conjecture
Calculation:
Determine the three lengths DE, EF and DF among the given three points D, E, and F.
The three points D, E, and F are collinear, if the sum of the lengths of any two line segments among DE, EF and DF is equal to the length of the remaining line segment.
That is
Thus, the conjecture
