the horizontal leg for the smaller triangle is three. The ratio for the vertical leg to the horizontal leg is ninety over three. The vertical leg for the larger triangle is two hundred ten and the horizontal leg for the larger triangle is seven. The ratio of the vertical leg to the horizontal leg is two hundred ten over seven. We can simplify both of these ratios to thirty over one. In Step E, we will Examine Your Results. Does your answer make sense? Here compare your answer to the question. Yes my answer makes sense, because I found the slope. Is your answer reasonable? Here compare your answer to the estimate. Yes, because thirty is the same as about thirty. And is your answer accurate? Here check your work. Yes the answer is accurate. We can now write your answer in a complete sentence. The change in vertical distance over horizontal distance is thirty feet per minute. CLOSURE Now let’s go back and discuss the essential questions from this lesson. Our first question was, what does corresponding mean? Corresponding means having the same relationship, such as angles and sides. Our second question was, how do you determine similarity? If two triangles are similar, the measures of their corresponding sides are proportional. And our third question was, how is the slope of a line related to the similar slope triangles formed by the line? The ratio of the vertical leg to the horizontal leg of each similar slope triangle formed by the line is equal to the slope of the line.
