Write the ratio of corresponding sides for the similar triangles and reduce the ratio to lowest terms. 2 similar triangles. Triangle 1 has side lengths 4, 5, blank. Triangle 2 has side lengths 12, 15, blank. A. Startfraction 4 over 5 endfraction = startfraction 12 over 15 endfraction = startfraction 4 over 5 endfraction b. Startfraction 4 over 15 endfraction = startfraction 5 over 12 endfraction = startfraction 4 over 15 endfraction c. Startfraction 4 over 12 endfraction = startfraction 5 over 15 endfraction = startfraction 1 over 3 endfraction d. Startfraction 5 over 4 endfraction = startfraction 15 over 12 endfraction = startfraction 5 over 4 endfraction.
