Answer:


Step-by-step explanation:

Short answer No They are not congruent. The scale factor would be 1 if they were. JL and RT should both be the same length (they are opposite angles marked with 2 quarter circles). They are not equal. So the scale factor is not 1.

To get from JKL to RST you must multiply every length of JKL by = 20 / 25 or 4/5. So 15 * 4/5 = 12 which works. 4/5 * 20 = 16 which also works.

The two triangles are similar.
