In a right triangle, the largest side is called the hypotenuse. Furthermore, from the Pythagorean Theorem, the following relation is satisfied:
[tex]c^2=a^2+b^2[/tex]To find if those measures correspond to a right triangle, verify if it satisfies the Pythagorean Theorem:
[tex]\begin{gathered} 1.25^2=1.5625 \\ 1^2+0.75^2=1.5625 \end{gathered}[/tex]Then:
[tex]1.25^2=1^2+0.75^2[/tex]Therefore, the sides of lengths 1.25 in, 1 in and 0.75 in are indeed the sides of a right triangle.
