Example 1:To determine the width of a river, Naomi finds a willow tree and a maple tree that are directlyacross from each other on opposite shores. Using a third tree on the shoreline, Naomi plantstwo stakes, A and B, and measures the distances shown.Find the width of the river using the information that Naomi found. Important: In order to usethe scale factor you must first prove the two triangles are similar.Willow9.3 mMapleSumac8.4 mB24 m

Refer to your pictures and pick one pair that you believe are congruent and one pair that you believe are similar based on the copies you have made on the coordinate plane. Using a protractor and a ruler, prove that the pair is congruent and the other pair is similar. Remember, you will need to use the side lengths and the angles measures. Make sure to include the scale factor between your two similar shapes. Which pictures did you decide were congruent? Provide all of your information and copies of your pictures to prove they are congruent. Which pictures did you decide were similar? Provide all of your information and copies of your pictures to prove they are similar. Attach all your evidence.
