## Homework Statement

Find the sides of isosceles triangle with perimeter 17, if the sides are integers.

## Homework Equations

N/A

## The Attempt at a Solution

The perimeter is equal to 2b+a=17

Now a=17-2b, so b = {1,2,3,4,5,6,7,8} and a= {15,13,11,9,7,5,3,1}

But in my book results the answers are (7,5,5), (5,6,6), (3,7,7), (1,8,8)

What are the rules for isosceles triangle. Must 2b > a ?

Thanks in advance.
