Answer:
D.) 4m, 11m, 9m
Step-by-step explanation:
According to the Triangle Inequality Theorem, the sum of any two sides of a triangle must be larger than the third side in order to form a triangle. Using the two shortest sides, you can find the sum and check to make sure it is larger than the third:
3m + 3m = 6m NOT greater than 6m
4m + 7m = 11m NOT greater than 12m
5m + 3m = 8m NOT greater than 9m
4m + 9m = 12m YES greater than 11m
It is a right Right Triangle because, they have two equal sides.
