Question

Circle F is congruent to circle J, and ∠EFD ≅ ∠GJH. m∠DFE = 80°. What is the measure of Arc GH? °

Answer 1

Answer:

arc GH=80°

Step-by-step explanation:

we know that

If circle F is congruent to circle J

and

∠EFD ≅ ∠GJH

then

arc GH ≅ arc ED

Find the measure of arc ED

arc ED =∠EFD -----> by central angle

so

arc ED=80°

therefore

arc GH=80°
