ok the two read angles are equal to each other because they are complementary

if i remeber correctly the only thing we can conclude is that when we add the two angles togther we get 90 degrees... how does that necessarily mean they are equal? How do we even know they are complementary? I remeber in geomentry we did statement and reason proofs like so

statements | reasons
________________________

were the statements would be just statements and the reasons are why the statements are true...

also I still don't see the triangle =[, even looking at it from the red thetas that i've been told are complemetary,
i labeled the forces with the names of the parts of the triangles they must be in order for us to resolve into it's components...

however i still don't see the triangle...
