The measure of D is 52 degrees, the measure of E is 90 degrees and the measure of F is 52 degrees.

When looking at similar triangles the ratio of side has nothing to do with the angles. Similar triangles will have similar angles in the same order.

I will tell you that you do definitely have at least one measurement wrong in the first triangle though as those do not add up to 180 and this won't produce a triangle.
