Angles are measured using a protractor

When the angle you are measuring is obviously an obtuse angle (angle above 90 degrees, or when you draw a box in the angle and it turns out bigger than it's supposed to) you use the big numbers. When the angle is obviously acute (opposite definition of obtuse), you use the little numbers.

There are special angle-measuring instruments which you can use to measure the angle.

We would typically use a sextant to measure the angle of a star above the horizon.
An angle measuring more than 90 degrees is obtuse. An angle measuring less than 90 degrees is acute. An angle measuring 90 degrees is right.

To use a protractor effectively for measuring angles accurately, place the center of the protractor on the vertex of the angle. Align one side of the angle with the 0-degree mark on the protractor. Read the measurement where the other side of the angle intersects the protractor. Make sure to use the correct scale (either 180 degrees or 360 degrees) based on the type of angle you are measuring.

To calculate a congruent angle, you need to identify an angle that has the same measure as a given angle. For example, if you have an angle measuring 45 degrees, any angle measuring 45 degrees is congruent to it. You can use a protractor to measure angles accurately. If you need to find a congruent angle in a geometric figure, look for corresponding angles created by parallel lines and a transversal, or use properties of triangles and other shapes.
When measuring an angle you have to measure the sides using a protractor.
