How do u find similar figures when using a proportion?'cause I don't get it dude.

**EXAMPLE-On two sides-72m
On the other 2-45m
The next one says
On one side-50m
On the other- 80m
Determine whether they are similar.
I don't get it. Please help!
THANX!

it takes robert three fifth of an hour to ride his bike between his house and his aunts house.if he needs to ride from his house to his aunts house and then back home about how long will it take him

what sides correspond?

huh?

like you know in a traingle when there 3 sides and one long side one shorter side and one shortest
well in the 2 figures whne your trying to find if a figure is similar you have to make sure the sides your comapring ar alike in size menaing there corresponding
soo which sides go togeher

oh. um.....ok. Well there are numbers and how do you know the total equality of the sides?

i thought you were asking about proportions lol

weny needs 2 thirds yard of blue felt and one 12 yard of red feltto make a banner how much felt in yards does he need

Do the proportion:

72/45 as ? 80/50

check the numbers:
8*9/5*9 as? 8*10/5*10
and it checks, 8/5 on both sides.

Well I kinda am asking about proportions and similar figures. But also finding out the proportions to see if both triangles are similar. Do u get it.... I sure don't!

ok THE DUDE stop trying to impersonate me and next, Sara was on the right track.

i do not know!!!!

find x
short side=10
long side=16
find value for x

This dude is seriously having a conversation with himself like he's crazy *facepalm*

and Hello from a decade into the future

To find the value of x, you can set up a proportion using the ratios of the corresponding sides. In this case, you have a triangle with a short side of 10 and a long side of 16. Let's call the unknown side x.

To set up the proportion, you can compare the ratio of the short side to the unknown side with the ratio of the long side to the known side:

short side / unknown side = long side / known side

Substituting the known values into the equation:

10 / x = 16 / 16

Now, you can cross-multiply, which means multiplying the numerator of the first fraction with the denominator of the second fraction and vice versa:

10 * 16 = x * 16

160 = 16x

To solve for x, divide both sides of the equation by 16:

160 / 16 = 16x / 16

10 = x

Therefore, the value of x is 10.
