उत्तर
Take a = 12, b = 13 and c = 15
Now a2 + b2 = 122 + 132
= 144 + 169
= 313
152 = 225 ≠ 313
No, By the converse of Pythagoras theorem, the triangle with given measures is not a right angled triangle.

In ∆LMN, l = 5, m = 13, n = 12 then complete the activity to show that whether the given triangle is right angled triangle or not.
*(l, m, n are opposite sides of ∠L, ∠M, ∠N respectively)
Activity: In ∆LMN, l = 5, m = 13, n = `square`
∴ l2 = `square`, m2 = 169, n2 = 144.
∴ l2 + n2 = 25 + 144 = `square`
∴ `square` + l2 = m2
∴By Converse of Pythagoras theorem, ∆LMN is right angled triangle.
