please makr as brainliest!!

thanks!!!

Step-by-step explanation:

the rule for a right angled triangle's sides is

a² + b² = c²

if this holds true for the given dimensions and RHS = LHS, then these can form a right angled triangle

3² + 4² = 5²

9 + 16 = 25

25 = 25

LHS = RHS

thus, these can be the dimensions of a right angled triangle.
