if angle a is congruent to itself by the reflexive property, which transformation could be used to prove δabc ~ δade by aa similarity postulate?

translate triangle ade so that point d lies on point b to confirm ∠d ≅ ∠b.
translate triangle ade so that point b lies on point e to confirm ∠b ≅ ∠e.
dilate δabc from point a by the ratio segment ad over segment ab to confirm segment ad ~ segment ab.
dilate δabc from point a by the ratio segment ae over segment ac to confirm segment ae ~ segment ac.

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

a reflection across the x axis and a 90 degree rotation left and right.
