Answer:
(A) No
(B) Yes
Step-by-step explanation:
(A) Using centimeters for example, it is not possible to create a closed or full triangle with side lengths 1cm, 5cm and 3cm. [See attachment for illustration]
(B) It is possible to create a triangle of side lengths 3cm, 4cm and 5cm. [See attachment also]
The Pythagoras Rule also applies in this case.
The sum of the squares of the lengths of the 2 shorter sides (the opposite side and the adjacent side) is equal to the square of the longest side (the hypotenuse).
(3×3) + (4×4) = (5×5)
9 + 16 = 25
