Answer: This triangle is not a right triangle
Explanation:
To find this you can use the set up for the pythagorean theorem. The hypotenuse is the c while the other sides are a and b.
[tex]{a}^{2} + {b}^{2} = {c}^{2} [/tex]
After setting it up you add in the numbers
[tex] {8}^{2} + {16}^{2} = {18}^{2} [/tex]
Then square them
[tex]64 + 256 = 324[/tex]
Then you add the two sides together
[tex]320 = 324[/tex]
If they are equal then it is a right triangle. While if they are not equal it is either obtuse or acute.
Sorry if this is long or doesn't make sense.
