Consider the following diagram.  What are the lengths of AE and CE?

hints: 

 

AE: sin 45 degrees = AE/1

CE: cos 45 degrees = CE/1

 

using the fact that:

sin = opposite/hypotenuse

cos = adjacent/hypotenuse

 

easy way to remember sin, cos, & tan: sohcahtoa

 

hope this helped.

They are both the same length

Using Pythag Theorem

s^2 + s^2 = 1^2

s = sqrt ( 2)  / 2
