    9,15,18 and the other is 6,10,12 but 3/2*6,3/2*10,3/2*12 = 9,15,18 if u multiply all the sides by 3/2

    the angles within the triangle are dependant on the ratio of the sides to one another, not the actual side length

    if you know the sin law or the cos law for example, u can show that the same 3 angles in the left triangle will exist in the right triangle

    another way to show similiaright is to label the triangle and show same propotions exist

    you have to show 3 sides are proportional thats about it u can go about it other ways

    i personally thing stating that all the sides of the bigger triangle are 3/2 factor bigger than the sides of the smaller triangle is good enough

    okay :) wow, that;s really helpful, but what about number 12? I just can't say that it have 4 right angles ( square have it to).

    is 8/20 = 12/25?

    or 8/12 = 20/25?

    the first one I think? let me check 8/12 = 12/ 25 2/3 =12/ 25 ( false) 8/20 = 20/25 2/5 =4/5 ( false )
