the legs of a triangle are 3 and 6 the third leg could between which two values
The third leg of a triangle must be greater than the absolute value of the difference between the other two legs and less than the sum of the other two legs.
In this case, the two legs are 3 and 6. The absolute value of the difference between the two legs is |3 - 6| = 3.
Therefore, the third leg could be between 3 and 9 (3+6) or between -3 and -9 (-3-6).
