CPM Homework Help : INT2 Problem 2-85

One possible proportion for the similar triangles below is $\frac { A C } { A B } = \frac { D F } { D E }$ . Write at least three more proportions given that $∆ABC\sim ∆DEF$ .

Triangle A, C, B, where angle, A, has 1 tick mark, and angle C, has 2 tick marks.

Triangle D, F, E, where angle, D, has 1 tick mark, and angle F, has 2 tick marks.

Step:

Using this proportion, think of at least two more proportions to satisfy the question.

$\frac{BC}{EF}= \frac{AB}{DE}$
