The circumference of isosceles triangle is 12cm, the difference between one side and the other side is 3cm, and the length of three sides is 3cm______ ．

The circumference of isosceles triangle is 12cm, the difference between one side and the other side is 3cm, and the length of three sides is 3cm______ ．

There are two situations: 1) when the difference between the waist and the bottom is 3cm, the waist is 5cm, the bottom is 2cm, 5, 5, 2 can form a triangle, which is in line with the meaning of the title; 2) when the difference between the bottom and the waist is 3cm, the bottom is 6cm, the waist is 3cm, 3, 3, 6 can not form a triangle, which is not in line with the meaning of the title

The difference between the two sides of an isosceles triangle is 8, and the sum of the bottom and the waist is 18

Let one side be x and the other side be y
{x-y=8
{x+y=18
Solution
{x=13
{y=5
Because 5 * 2

The center line on the waist of an isosceles triangle divides the circumference of the triangle into 20 and 36, and finds the length of each side of the triangle

The length of isosceles is 24, the length of base is 8
