easy using trigonometry,
first evident C = 45, (triangle rectangle dans un carré)
tan(A) = 1/3 ==> A = 18,43
tan(B) = 1/2 ===> B = 26,57,

which gives C = A + B

OK here's another one

Rays Through the Squares



Using only elementary geometry (not even trigonometry), prove that angle C in the illustration equals the sum of angles A and B.

I can't see the solution using elementary geometry a hint?

Salaam Khti Damya,

Indeed it's easy using trigonometry...I'm not that gentle! ...tell her dear rival

ehm....


a+b are the small angles which are less than 90° which are the acute angles.
and when put together they make the same angle as C which is set at 45 degrees
was that parellelograms or something? I can't even remember that far back!
