Question

A triangle has sides of length 6, 8, and 10. Is it a right triangle? Explain.

Answer 1

Answer:

yes because according to the Pythagorean theorem  

Step-by-step explanation:

Answer 2

Yes it is, assuming we decide to use the Pythagorean Theorem to find the hypotenuse (10) it'll be possible considering the formula is c²=√a²+b²
(c being the longest side of the triangle)
a= 6 and b= 8

c² =√6² + 8²
  c² = √100     square root of 100 equals 10
 c= 10
