With a ruler
Yes, two arcs with the same measure that are arcs of the same circle or congruent circles are congruent to each other. This means they have the same length and subtend the same angle at the center of their respective circles. Therefore, if the circles are congruent, the arcs will be identical in measure, regardless of the size of the circles.
The question, as posed, makes little sense. All that they would find is the points of intersection of the circles! The question says nothing about the sizes of the circles - whether they are the same or whether they represent some measure of seismic transmissivity of the earth near (under) them.
How can a circle measure 180 degrees? Circles don't have any angles!
Two arcs are congruent if they have the same measure in degrees or radians, and they belong to the same circle or to congruent circles. This means that their lengths are equal, and they subtend the same central angle. Additionally, congruent arcs can be thought of as having identical properties, even if they are located in different congruent circles.
Yes because they can be measured mathematically. But free form shapes can't for instance you can't measure a pare using i ruler. But you can measure a square with a ruler.
they use protractors to measure circles
They are circles. We measure circles in degrees.
Protractors have to be half- circles because they measure angles less than 360 degrees.

To use a protractor for circles you find the middle of the circle and you then put the dot on the hole then you measure
Congruent circles, maybe...
Congruent Arcs
Archimedes of Syracuse
For the same reason they chose to measure volume in cubic units
A protractor measures the degree of angles and circles.
same circle or congruent circles
Yes; the circle is a special case of an ellipse.
