Question

How many isoceles triangles are there if each of its sides have an integral length and it's perimeter is 144​

Answer 1

`\sf \: 34 \: isosceles \: triangle \: - - - - - - - - - - - - - - - - - - - - - - - -`

Explanation:

`b = 144 - 2a < 2a`

So, that

`a > 36`

and 2a < 144 so that

`a < 72`

since a = b implies a = 48

{37,38,39.......71}/{48}

There are 71-37 = 34 isosceles triangle
