Solution

1

Explanation:


Let ABCD be the given square.

In ∆ABC,

∠B = 90°

∴ AC2 = AB2 + BC2    ...[Pythagoras theorem]

∴ `(sqrt(2))^2 = AB^2 + AB^2`   ...[Sides of the square]

∴ 2 = 2AB2

∴ AB2 = 1

∴ AB = 1 unit

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.
