Question

What is the perimeter of the following polygon?

Answer 1

the bottom of the triangle is how many units long?

Answer 2

isn't it 16

Answer 3

yes

Answer 4

it wants you to find the perimeter so you have to first find the hypotenuse

Answer 5

the triangle is made up of two smaller triangles so you have to find the hypotenuse of one of them

Answer 6

since the bottom of both triangles combined is 16, what is the length of only one of those smaller triangles? HINT: its half of the bottom value

Answer 7

8

Answer 8

right. Are you familiar with the pythagorean theorem?

Answer 9

yup
a2+b2=c2

Answer 10

okay, so, you have a and b now find c. A=8 and b=15. find C. dont forget to square them

Answer 11

do you know how?

Answer 12

yea

Answer 13

okay, so what is the length of the hypotenuse or one of the smaller triangles?

Answer 14

yup so now you have the value of the bottom of the triangle and the value of both sides. To find the perimeter you have to add the values of all the sides. So whats the perimeter of the triangle?

Answer 15

the sides lengths are 16 17 and 17. whats the perimeter?

Answer 16

50?

Answer 17

yup! good job!
