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.
3 angles
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

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.
The 3 interior angles of any triangle add up to 180 degrees and the 3 exterior angles add up to 360 degrees
A decagon will always have its interior angles measure 1480
If there were not that difference of 3o, the angles would be 60 and 30. Because of the difference the angles must be 61o and 29o.
Equilateral triangle.
