Angles in congruence triangles

View attachment 8476

I am trying to work out the above problem.
Known are: D,A,B,a,c,d. I need to work out b,d,G and F. Any ideas?

c+d = 90 degrees.

Regards,

Stan

Hi, and welcome to the forum!

A am not sure we can find F because I don't see any constraint that prevents one from making F longer while preserving D, A, B, a, c, and d.

Also, what congruent triangles do you mean in the thread title?
