Question

A triangle with sides of lengths 16,30,and 35 is a right triangle? a. true b. false

Answer 1

 
-- The square of the shortest side . . . 16² = 256
-- The square of the medium side . . . 30² = 900
-- Their sum . . . (256 + 900) = 1,156

-- The square of the longest side = 35² = 1,225

1,156 and 1,225 are not equal, so these 3 numbers
can be the sides of a triangle, but it's not a right one.

The statement is false. (choice 'b')
