Pythagoras

[tepid zephyr]

When doing Pythagoras, do you always need to square root the 2 numbers?

[north thistle]

a^2+b^2=c^2

a^2=b^2-c^2

[tepid zephyr]

so you dont need to square root?

[north thistle]

a^2= 12.6^2-5.7^2
a^2 = that answer
a = sqrt of that answer

you cant have a squared length

has to be sqrted
