Answer:
No
No
Step-by-step explanation:
In a right angled triangle :
The square of the length of the longest side is equal to the sum of the squares of the two remaining sides : - Pythagoras
That is :
a² = b² + c² (condition must be satisfied).
9m, 4m, 5m
9² = 4² + 5²
81 = 16 + 25
81 ≠ 41 (not right angled)
5cm, 12cm, 14cm
14² = 12² + 5²
196 = 144 + 25
196 ≠ 169 (not right angled)
