The polygons have congruent angles (∠ABC = ∠FGH = 103°, ∠BCD = ∠GHE = 84°) but not all corresponding sides are proportional (AB/FG ≠ BC/GH ≠ CD/HE ≠ DA/EF), indicating they are not similar.

Given:

Angles:

∠ABC = ∠FGH = 103°

∠BCD = ∠GHE = 84°

We need to find:

∠DAB and ∠FEH

Finding ∠DAB

The sum of interior angles in a quadrilateral is 360°.

∠DAB = 360° - (∠ABC + ∠BCD + ∠CDA)

∠DAB = 360° - (103° + 84° + 95°)

∠DAB = 360° - 282°

∠DAB = 78°

Finding ∠FEH

Using the same logic:

∠FEH = 360° - (∠FGH + ∠GHE + ∠HEF)

∠FEH = 360° - (103° + 84° + 95°)

∠FEH = 360° - 282°

∠FEH = 78°

Therefore, both ∠DAB and ∠FEH are 78°.

Now, let's move on to the side lengths to check for proportionality.

Given side lengths:

AB = 2014, BC = 1611, CD = 2014, DA = 1861

Checking for side length proportionality

For two polygons to be similar, their corresponding sides must be in proportion.

AB/FG = BC/GH = CD/HE = DA/EF

AB/FG = 2014/107 = 18.79

BC/GH = 1611/84 = 19.18

CD/HE = 2014/107 = 18.79

DA/EF = 1861/936.5 = 1.99

Since not all corresponding sides have the same ratio, the polygons are not similar.

Therefore, after analyzing both angles and side lengths, the conclusion remains: the two polygons are not similar.
