Question

Circle F is congruent to circle J, and ∠EFD ≅ ∠GJH. Circles F and J are congruent. Line segments F E and F D are radii. A line connects points E and D to form a triangle. Line segments J H and J G are radii. A line connects points H and G to form a triangle. Angles D F E and G J H are congruent. m∠DFE = 80°. What is the measure of arc Arc G H? °

Answer 2

`mGH=80^\circ`

Explanation:

Circle F and J are congruent.

`\angle DFE \cong \angle GJH`

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

`mGH=\angle DFE = 80^\circ`

The measure of arc GH is 80 degrees.
