    There are no pictures... I guess we supposed to use our imagination.

    is that 2:3 a ration of triangle to triangle? or is it one side of a triangle to another side of the same triangle?

    are these right tris or any tris will work?

    see area is always proportional to the square of the ratio. so area will be at a ratio of 4:9

    I think any triangle will work, I'm not sure I copied the question exactly the way it appears on my sheet. I think its talking about sides that correspond.

    Dipankarstudy I'm confused at what you just said to be honest, I kinda bad at math, I missed this whole topic

    2:3 --- 4:6 so if we have a tri with sides 2 and 3; we can make another with sides 4 and 6 right?

    ok..... the sides have a 2/3 ratio....got it; let me draw a pic

    see for a similar triangle the sides are in proportion. see the attach ment... where the triangles are similar area of a triangle=base*hight/2; area abc 0.5*bc*ad 2*2 ------- = -------- = ----- =4/9 area def .5*fg*eh 3*3 ad and eh are also will be in the same ratio as the trin 'abd' and 'efh' are similar....

    this would be similar tris with a 2:3 ratio

    To be honest Im very confused the question seems to be a short answer with the space provided, and not that complicated.

    Yea, but Im very confused and don't understand the question at all. The ratio part and the corresponding sides is really confusing me

    we can determine the ration of altitudes by comparing the side*sin ratio

    the ration just means that corresponding sides should equal 2/3 when written one on top of the other..

    is the 2sin(30) the 3sin(30) a ration of 2/3 ?

    in other words: is: 2 sin(30) ------- = 2/3 ? 3 sin(30)
