Question

In triangle ABC, angle BAC = angle ACB = 45° , angle ABC = 90° , AC =2√2, A
find AB​

Answer 1

Answer: AB = 2 cm

Step-by-step explanation:

In the above triangle, BAC = ACB = 45°

then every opposite side of these angles are equal

So, AB = BC

let, AB = BC = x cm

By the Pythogoras theorem,

x^2+x^2 = (2√2) ^2

, 2x^2 = 8

, x = √4 cm

, x = 2 cm
