A is quadratic function
B is equation of a circle
C is equation of a line
D is hiperbolic funciotn
The first one is congruent by ASA. The second does not have to be congruent, we don’t know enough.
Answer:

Step-by-step explanation:
Circle F and J are congruent.

Given that: m∠DFE = 80°
DFE is the central angle of the circle F.
The measure of arc GH is equal to the central angle of Circle J.
Since both circles are congruent

The measure of arc GH is 80 degrees.
