Question

Can 14,18 and 19 form a triangle?

Answer 1

To confirm if this can form it, we take the lower of the two numbers , square them, and equal it to the biggest number squared. (AKA The Pythagorean Theorem).

Explanation:

`14^(2) +18^(2) = 19^(2)`

Now solve to see if it equates to be true.

196 + 324 = 361

520
`\\eq` 361

That means 14, 18, and 19 can't form a triangle.

Answer 2

Yes

Explanation:

Using the triangle formula: a+b>c , b+c>a , and c+a>b, we can conclude that these values can form a triangle because 14+18>19 , 14+19>18 , and 18+19>14.
