Answer:

see the explanation

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of arc EH

Remember that the measure of the complete circle is equal to 360 degrees

so

[tex]arc\ EH+arc\ EF+arc\ FG+arc\ GH=360^o[/tex]

Remember that

[tex]arc\ EF=m\angle EDF[/tex] ----> by central angle

[tex]arc\ FG=m\angle FDG[/tex] ----> by central angle

[tex]arc\ GH=m\angle GDH[/tex] ---> by central angle

substitute the given values

[tex]arc\ EH+55^o+70^o+110^o=360^o[/tex]

[tex]arc\ EH=360^o-235^o=125^o[/tex]

step 2

Which arc is congruent to Arc E H?

we know that

[tex]arc\ EFG=arc\ EF+arc\ FG=55^o+70^o=125^o[/tex]

therefore

arc EH is congruent with arc EFG

or

arc EH is congruent with minor arc GE
