Question

начерти ломаную из трех звеньев так,чтобы длина ее была равна 12 см,а второе звено было на 2 см длиннее первого и на столько же см короче третьего

Answer 1

12+2-2=12 см
12:3=4 см - 1 отрезок
4+2=6 см - 2 отрезок
4-2=2 см - 3 отрезок.

Answer 3

Drawing a Broken Line with Three Links

To draw a broken line with three links, where the length of the line is 12 cm, the second link is 2 cm longer than the first link, and the third link is as short as the second link, we can follow these steps:

1. Start by drawing the first link, which is the shortest. Let's call it Link A. 2. Draw the second link, which is 2 cm longer than Link A. Let's call it Link B. 3. Finally, draw the third link, which is as short as Link B. Let's call it Link C.

To ensure that the total length of the line is 12 cm, we need to distribute the lengths of the links accordingly. Since Link A is the shortest, we can assign it a length of 2 cm. Link B will be 2 cm longer than Link A, so its length will be 4 cm. Finally, Link C will have the same length as Link B, which is 4 cm.

Here is a visual representation of the broken line:

     A (2 cm)       B (4 cm)       C (4 cm)

Please note that the lengths of the links are not drawn to scale in this representation.
