Question

Find side of square whose
diagonal is 8√2 by 45° 45° 90° theoram.​

Answer 1

Let the sides of square be 'a'

by 45°45°90° theorem

by Pythagoras theorem

=> a^2 + a^2 = (8√2)^2

=> 2a^2 = 64×2

=> 2a^2 = 128

=> a^2 = 128/2

=> a^2 = 64

=> a = √64

=> a = 8 units or cm or whatever the unit is write that

Side of square is 8
