Explain why the triangles are similar. Then find the missing length, x. 4 in. 21 in. 7 in. ..... Choose the reason that the triangles are similar. O A. Both triangles are right and scalene. O B. The Pythagorean theorem states that a +b = c. Thus, the corresponding sides are proportional. C. One angle pair is given to have the same measure (right triangles). Another angle pair consists of vertical angles with the same measure. Thus, two angles of the large triangle are equal in measure to two angles of the small triangle. D. All right triangles are similar.
