Please answer fast!!(15 points) Use the Pythagorean theorem to prove if a triangle with side lengths 7,14,28 is a right triangle

Taking 28 as the hypotenuse

If √ 7 ² + 14² = 28 then it's a right angled triangle

√7² + 14² = √ 49 + 196

= √ 245

= 7√5

Since it's not equal to 28 the lengths

7 , 14 , 28 is not a right angled triangle.
