Question

mathhhhh

Answer 1

since its an square what do u do to the missing sides

Answer 2

well they would be the same

Answer 3

how can we understand that it REALLY is a square though?

well says that"this figure is a REGULAR polygon", what the above reply didnt mention -- he just eye guessed it most likely

if it wasnt a regular polygon we would get into quadratic formula and bllahbllah, BUT since it is we can say it is a square.
thus,
\[ x^2+4=x^2+x \]
\[ x^2+4-x^2=x^2+x-x^2 \ \ \ \ \ \ \ \ \ (\text{writing this just so you see what i did)} \]
\[ 4=x \]
so nah yeah

Answer 4

oh ok
