Answer:
No
Step-by-step explanation:
In every right triangle, where "a" and "b" are the legs of the right triangle and "c" is the hypotenuse (This is known as "Pythagorean's theorem). To figure out if a triangle with side lengths 6, 8, and 11 inches is a right triangle, all you have to do is plug in the values 6 and 8 for "a" and "b" and the value 11 for "c" to get":
This simplifies to:
Which simplifies further to:
This is obviously incorrect so therefore, the triangle lengths given do not form a right triangle.
Hope this helps :)
