Question

Q11. Is the trangle with sides 11 cm, 13cm and 14cm a right trangle?
Give reason.​

Answer 1

Answer: No

Step-by-step explanation:

A right angled triangle will follow Pythagoras' Theorem

11² + 13² = 121 + 169 = 290 ≠ 14²

Therefore, the triangle with sides 11 cm, 13 cm and 14 cm is not a right angled triangle.  

(14 is taken as hypotenuse as it is the longest side)
