A protractor is a circular or semi circular instrument for measuring angles and some have existed from ancient times. A half circular protractor is marked for 180 degrees and a full circle for 360 degrees. Protractors usually have two sets of numbers going in opposite directions, so be careful which side you use. When in doubt you should ask yourself is the angle greater or smaller that 90 degrees.

What is the sum of the measures of a dodecagon?
It depends on what the measures relate to: lengths of sides, interior angles, exterior angles, ...
The sum of the measures of the interior angles of a heptagon?
The sum of the measures of the interior angles of a heptagon is 900 degrees.
What are the measures of the other three angles of the parallelogram if one of the angles measures 130 degrees?
50°, 130°, and 50° are.
What are angles that have the same degree measures?
They are equal (or 'congruent') angles.
Why do complementary or supplementary angles not have to be adjacent?
complementary angles measures add to 90 and supplementary angles measures add to 180. Whether they are next to each other or not does not matter.
What instrument measures triangles?
The instrument for measuring the angles of a triangle is called a protractor.
What instrument measures angles in degrees?
A protractor is one such instrument. Navigational aides that do the same include compasses and sextants.
What do you call the instrument that measures the angles formed by the line of sight to the north star and the horizon?
Azimuth
What is the name of the instrument for measuring slope angles?
The instrument used for measuring slope angles is called an inclinometer or clinometer. An inclinometer typically measures the angle of a slope relative to a horizontal plane, while a clinometer can also be used for measuring angles of elevation or depression. Both tools are essential in fields such as surveying, geology, and construction.
What does a protractor measure?
A protractor measures the degree of angles and circles.
Angles with equal measures?
congruent angles
Two angles whose measures total 180 are called what?
Supplementary angles are 2 angles whose measures = 180o.
What is complementary angles and suplementary angles?
Two angles are complementary if the sum of their measures is 90 degrees.Two angles are supplementary if the sum of their measures is 180 degrees.
What are subplementary angles and complementary angles?
Two angles are complementary if the sum of their measures is 90 degrees.Two angles are supplementary if the sum of their measures is 180 degrees.
What instrument measures degrees?
An instrument that measures degrees is called a protractor. Protractors are primarily used in geometry to measure angles in degrees. They typically have a semicircular or circular shape, with markings that indicate the degree measurements from 0 to 180 degrees or 0 to 360 degrees, depending on the design. Other instruments, like theodolites, also measure angles in degrees, particularly in surveying and construction.
