Answer:
The measure of arc GH is 80 degrees.
Step-by-step explanation:
Circles F and J are congruent.Given that: m∠DFE = 80°
Angle DFE serves as the central angle of circle F.
Arc GH's measurement corresponds with the central angle from Circle J.
Since the two circles are congruent
The measure of arc GH, therefore, is 80 degrees.

Answer:
For a clearer understanding, refer to the attached figure:
Step-by-step breakdown:
1. According to the unique line postulate, only one line segment can be created: BC
This is because a single line can only connect two distinct points.
2. Utilizing the definition of reflection, reflect BC across l.
To identify the line segment reflected over l, we will apply the reflection definition.
3. Based on the reflection definition, C remains as its own image and A represents the image of B.
The reflection definition states that a figure is transformed into a mirror image around a line. Thus, CD serves as the perpendicular bisector of AB, which makes A and B equidistant from D, producing their mirror images.
4. Because reflections maintain length, we find that AC = BC
In a reflection, the figure transforms to create a mirror image, ensuring the lengths remain unchanged.
