Triangles ABC and DEF are similar. Find the length of segment EF?

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

they can either have 0,1, or infinite solutions

step-by-step explanation:

transitive property

step-by-step explanation:

the definition of the transitive property is:

if a = b, and b = c, then a = b
