Protractor, Inclinometer (often shortened to Clinometer), Theodolite.
You could also add Compass and Sine Bar (though the latter really sets rather than measures an angle).
The 3 interior angles are 90 degrees, 45 degrees and 45 degrees
Yes, congruent angles are angles that have the same measure.

Triangles have 3 interior angles that measure 180 degrees total.
The 3 interior angles of any triangle add up to 180 degrees and the 3 exterior angles add up to 360 degrees

Equaliteral Triangle
All 3 sides are equal in length and each of the 3 interior angles measure 60 degrees

The 3 interior angles of any triangle add up to 180 degrees and the 3 exterior angles add up to 360 degrees
In a parallelogram, opposite angles are equal in measure. Therefore, the angle opposite the 37-degree angle will also measure 37 degrees. The sum of the interior angles of any quadrilateral is always 360 degrees. Since opposite angles in a parallelogram are equal, the other two angles will also measure 37 degrees each.
A decagon will always have its interior angles measure 1480

Angles with the same angle measure are congruent.
