Q. Consider the two given triangles. Are they similar triangles? Use two proportions to support your answer.
Identify sides/angles: Step 1: Identify corresponding sides and angles of the triangles to set up proportions.
Set up first proportion: Step 2: Set up the first proportion using sides DEAB=EFBC. Assume AB=4cm, DE=8cm, BC=6cm, EF=12cm. Calculate DEAB and EFBC.
Set up second proportion: Step 3: Set up the second proportion using sides AC/DF. Assume AC=5cm, DF=10cm. Calculate AC/DF.
Compare results: Step 4: Compare the results of the proportions. If all corresponding sides have the same ratio, the triangles are similar.
