Hi,

If two similar triangles have corresponding sides in the ratio 1:2, does it mean that their heights are also in the ration 1:2 ? (what about their perimeters, etc) ?

Thanks :)

Hi jbyx78,

You can actually PROVE the answer to your questions by coming up with a simple example:

Try drawing a 3/4/5 right triangle and a 6/8/10 right triangle and perform whatever calculations you're interested in.

Here, the ratio of side lengths between the two triangles is 1:2; you'll find that the ratio of heights is 1:2 and the ratio of perimeters is also 1:2. However, the ratio of the AREAS will be 1:4.

GMAT assassins aren't born, they're made,
