Given that the sides of a triangle are 2 cm, 4 cm, and 5 cm, for it to be a right triangle, the sides need to satisfy the Pythagorean Theorem:


\begin{gathered} 2^2+4^2=5^2 \\ \\ 4+16=25 \\ \\ 20=25\text{ \lparen Incorrect\rparen} \end{gathered}

Answer: The Pythagorean Theorem does not hold, so the triangle is not a right triangle.
