Use the given information to determine which​ lines, if​ any, in the figure to the right are parallel. Justify each conclusion with a theorem or postulate. 2 is supplementary to 3.

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

squares, rhombus, rectangles

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
