Question

How do you find the perimeter of a triangle with an unknown side length?

Answer 1

Like this triangle...

Answer 2

use the pythagorean theorem to look for the length of the hypothenuse (you have a right triangle)

Answer 3

what is the perimeter?

Answer 4

then add all the sides

Answer 5

Yep that is what you do

Answer 6

Took it right outta my head.Gj nincompoop

Answer 7

Could you explain how I would do that? @nincompoop or @jigglypuff314

Answer 8

(missing side)^2 = 12^2 + 6^2

Answer 9

ok the a is squared and the b is squared to equal the c squared like
12*12+16*16=c2

Answer 10

so 144+256= the c squared

Answer 11

Ok, now I'm getting confused...

Answer 12

the missing side is 20

Answer 13

(missing side)^2 = 12^2 + 16^2
so missing side = √(144 + 256)
= √(400)
=

Answer 14

see

Answer 15

do u understand now

Answer 16

So the missing side squared equals, 12 squared plus 16 squared? And this will give me the answer? So the missing side is 20.

Answer 17

yep :)

Answer 18

yes

Answer 19

the perimeter = all sides added up
= 12 + 16 + 20

Answer 20

but un have to divide 400 by the square root to find it

Answer 21

you

Answer 22

Thanks you both! I believe I understand now.
