They only have a difference of 2. Multiplying the small one by 2 equals the larger one. Doing the opposite and dividing 2 by the larger one gives you thee small triangle. they both have the same angles which makes them similar.
Pythagoras theorem is c^2 = b^2 + a^2
so when you plug in the numbers its 12^2 + 5^2 =169
which means 144+24=169
square root 169 = 13
AB =13 cm
