question 2 of 10
two arcs are congruent if they have the same measure and they belong
to ____ or to _____. (check all that apply.)

a. similar circles
b. congruent circles
c. similar triangles
d. the same circle

Explanation:

Congruent arcs require equal measure and must be in circles with equal radii. The same circle has identical radii, and congruent circles also have equal radii. Similar circles have proportional (not equal) radii, and triangles do not contain arcs in this context.

Answer:

B. congruent circles
D. the same circle
