AB = 8 cm
BC = 5 cm
By calculation, deduce whether triangle ABC is a right angled triangle.​

Answer 1

Answer:

9

Step-by-step explanation:

But it have another method.But in your question your doesn't mention which is right angle

Answer 2

$\textbf{☆ Solution -}$

⟹ AC = 22 - ( 8 + 5 )

⟹ 22 - 13 = 9

⟹ 9² = 81

⟹ 13² = 169 = 250

⟹ 22² = 484

⟹ Ans = ABC is not Right angle Triangle
