If a triangle has a perimeter of 52 units, then all its sides have length ________ units.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. <26.
If one side is 26, the other two sides must sum = 52 - 26 = 26
However, the sum of two sides must be greater than the third side, not equal to it.
Thus, no side can be 26 or greater.
Hence, all its sides have lengths <26 units.
