To find out how fast a tree grows, you can measure its trunk. a giant red oak's diameter was 248 inches in 1965. the tree's diameter had grown to 251 inches in 2005. find the average rate of change in the diameter of the tree per year.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
