Consider the two triangles.


To prove that the triangles are similar by the SSS similarity theorem, it needs to be shown that


i think the answer is 3? am i right? i added.

  1. AB = 25 and HG = 15
  2. AB = 30 and HG = 18
  3. AB = 35 and HG = 21
  4. AB = 35 and HG = 15

For the answer to the question above, you just simply use the Pythagoras theorem to find the 3rd length, a^2+b^2=c^2.
E.g 15^2+20^2= length of hypotenuse^2 
225+400=c^2
625=c^2
25=c
Which makes no. 1. AB = 25 and HG = 15 the answer. I hope this helps
