Question

Determine if the side lengths could form a triangle. 18 m, 21 m, 39 m

Answer 1

Answer:No,the side of lengths 18m,21m and 39m could not form a

Explanation:

To form a triangle, the sum of any two sides must be greater than the third side.

here,

18m + 21m = 39m

the sum to two side is equal to third side that is 39m

that's why these three sides cannot form any triangle

Answer 2

No

Explanation:

According to the first triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third ...

18 + 21 = 38 are not more than 39
