Determine the relation between the lengths or arcs pqr pab and bcr?
semicircle PQR of diameter 10 cm.semicircle PAB and BCR of diameter d1 and d2 respectively are inscribed in the semicircle PQR or such that the sum of d1 and d2 is equal to 10 cm. determine the relation between the lengths of arcs PQR,PAB, and BCR.
Only when they are the same lengths.
No. The first is a measure of length, the second is a measure of angular displacement. If you have two circles with arcs of the same angular measure, the lengths of the arcs will not be the same.
Two arcs are congruent if they have the same measure in degrees or radians and are parts of the same circle or circles of equal radius. Additionally, if the arcs are on different circles, they must subtend the same central angle. This ensures that the lengths of the arcs are equal, meeting the congruence condition.
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.
C.Measuring lengths of line segments by folding the paper and matching the endpointsB.Creating arcs and circles with the compass
To measure the length of a segment, you would use a straightedge. A straightedge provides a reference line to determine the distance between two points, while a compass is typically used for drawing arcs or circles rather than measuring lengths directly. Although a compass can help in constructing segments of a specific length, it does not measure length itself.

Advantages are that you can see the arc lengths disadvantages some times it doesn't work because of insufficient vertices's or arcs.
Volcanic arcs form at plate subduction zones. Island arcs are volcanic islands that form over "hot spots" in the Earth's mantle. Because the islands are moving with the oceanic plate, they eventually are removed from the hot spot, forming a chain of islands in the direction of the plate movement.
Any portion of the circumference of a circle is called an arc. Arcs can vary in length and are typically described as minor arcs (less than 180 degrees) or major arcs (more than 180 degrees). The endpoints of an arc are defined by points on the circle, and they help in distinguishing between different arcs.
To determine a midpoint, construct a line segment between two endpoints, A and B. Use a compass to measure the distance between A and B, then set the compass to half that length. From point A, draw an arc above and below the segment, and repeat from point B. The intersection points of the arcs give you two points that can be connected to form a perpendicular bisector, which will intersect the original segment at its midpoint.
