Question

Can the length 40 cm 42 cm and 9cm be the dimensions of a right angle triangle​

Answer 1

Answer:

yes it is right angle triangle

Answer 2

Answer:

Right angled triangle with these lengths is not possible.

Step-by-step explanation:

Pythagoras Theorem is applicable on Right Angled Triangle

If it follows the Theorem then, the lengths are possible.

Longest Side [Hypotenouse]  = 42 cm

∴ 42² = 40² + 9²

⇒ 1764 = 1600 + 81

⇒ 1764 ≠ 1681

Therefore, Right angled triangle with these lengths is not possible.
