When given 3 triangle sides, to determine if the triangle is acute right or obtuse
square all 3 sides
sum the squares of the 2 shortest sides
compare this sum to the square of the 3rd side
if sum > 3rd side squared it's an acute triangle
if sum = 3rd side squared it's a right triangle
if sum < 3rd side squared it's an obtuse triangle
24 32 42
24*24 = 576
32*32 = 1,024
42*42 = 1,764
Sum of the square of 2 shortest sides = 1,600
Since 1,600 < 1,764 these sides form an obtuse triangle.
