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.

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.
They are simply called intersecting arcs.
Yes, there can be congruent arcs on a circle. Arcs which subtend the same angle at the center are considered as congruent.
Draw a horizontal line AB equal to one of the side lengths. From A draw an arc of a circle of radius one of the remaining lengths. From B draw an arc of a circle of radius the third length. Where the arcs intersect is point C. Join AC and BC. Voila!
