The Hinge Theorem at Guden

The hinge theorem in geometry states that if two sides of one triangle are congruent to two sides of another triangle, and the included angle of the first is larger than the included angle of the second, then the third side of the first triangle is longer than the third side of the second triangle.  And as mentioned, the converse is also true.   I’m sure this makes sense somewhere!  Just in case you were needing to know this, I know I was a little curious when someone mentioned it.  Though it doesn’t relate to Guden Hinges at all, I’m usually interested in knowing how something termed “hinge” might work!
