Question

a. Find the ratio of the corresponding altitudes of two similar triangles in which the ratio of the corresponding sides is 2:3.

b. Find the ratio of the areas of two similar triangles in which the ratio of the corresponding sides 2:3.

Answer 1

is there pictures or are we sposed to use our imagination?

Answer 2

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

Answer 3

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?

Answer 4

are these right tris or any tris will work?

Answer 5

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

Answer 6

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.

Answer 7

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

Answer 8

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?

Answer 9

gonna have to take a min and brush up on that terminology :)

Answer 10

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

Answer 11

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....

Answer 12

this would be similar tris with a 2:3 ratio

Answer 13

i think u have understood.....

Answer 14

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

Answer 15

gotta work up to the answer; you wanna know the stuff right?

Answer 16

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

Answer 17

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

Answer 18

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

Answer 19

Oh okay

Answer 20

i dont know why i keep sticking that n onto my ratio wird lol

Answer 21

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

Answer 22

in other words: is:

2 sin(30)
------- = 2/3 ?
3 sin(30)

Answer 23

No it isn't I think -_-
