Fill in the blank for proofs please: 1. m Angles forming a linear pair sum to 180°

2. m _

3. m Transitive Property of Equality

4. m Algebra

5. FJG ≈ _

answer: group b.

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

my dear correct answer is option number 3
