The shapes are irregular and is formed by a octagon and a rectangle (square kinda = rectangle)
But given your multiple choice...
1) Shape 1 and 2 isn't congruent so false. 2) Shape 1 and 2 don't share the same coordinates because of a prior translation so false. 3) Shape 1 and 2 isn't congruent so false. 4) Shape 1 could be translated onto shape 2, but it still would not be congruent, so true.
Since all straight lines have an angle of 180 degrees if the exterior angle is equal to 113 degrees than you just subtract 113 from 180 which will equal 67.
