Sides of a triangle = 80, 160, 200. Find the sides of a similar triangle whose perimeter is 550cm rhubarb.

The ratio of the respective sides of similar triangles is equal to the coefficient of similarity. The ratio of the perimeters of such triangles is also equal to the coefficient of similarity. Find the coefficient of similarity of triangles, then multiply each side of the first triangle by it to find out the corresponding sides of the second.

Perimeter of the first triangle:

P = 80 + 160 + 200 = 440 cm.

k = 550/440 = 1.25.

Sides of the second triangle:

80 * 1.25 = 100 cm;

160 * 1.25 = 200 cm;

200 * 1.25 = 250 cm.

Answer: 100 cm, 200 cm, 250 cm
