The circumference of an isosceles triangle is 10 cm. First, the difference between the two parts divided by the middle line on the triangle is 6 cm

The circumference of an isosceles triangle is 10 cm. First, the difference between the two parts divided by the middle line on the triangle is 6 cm

Let the waist length be a and the bottom length be c
From the meaning of the title, 2A + B = 10
B-C = 6 or C-B = 6
Simulink B = 4-3 or B = 10-3 (rounding off)
Then B = 4-3

The bottom of the isosceles triangle is 10 cm long. The middle line of the upper waist divides the triangle into two parts. The perimeter difference between the two parts is 2 cm. The length of the isosceles triangle is 2 cm

Let the waist length be a
A + A / 2 = A / 2 + 10 + 2 or a + A / 2 + 2 = A / 2 + 10
A = 12 or a = 8

The length of the base of an isosceles triangle is 10 cm. If the difference between the two parts is 3 cm, the waist length is 10 cm______ ．

As shown in the figure, let the waist length of an isosceles triangle be xcm. When the difference between AD + AC and BC + BD is 3cm, that is 12x + X - (12x + 10) = 3, the solution is x = 13cm; when the difference between BC + BD and AD + AC is 3cm, that is 10 + 12x - (12x + x) = 3, the solution is x = 7cm. Therefore, the waist length is 7cm or 13cm
