Question

What is the length of side s of the square shown below?


A. 4
B. 4, square root of 2
C. 2
D. 8, square root of 2
E. 1
F. square root of 8

Answer 1

i would say 4 because usually a square is twice as long diagonally as it is horizontally

Answer 2

use the 45-45-90 rule => http://nanharbison.com/sats/math_images/45-45-90.gif
notice the ratios of relationships

Answer 3

in the 45-45-90 rule, the LONGEST side is \(\bf x\sqrt{2}\) and the other 2 sides, which are equal to each other btw, are "x"

so in this case it happens that your longer side is "8", that means that \(\bf 8 = x\sqrt{2}\)
to find "x", or that other 2 sides, solve for "x"
