A wire can besiege a city, a circle can t besiege a triangle, right?

No, a wire is the perimeter of a figure. It can be enclosed into a figure that can be thought of at will. A wire can be enclosed in a circle. It can also be enclosed in a triangle.

Wrong, a wire can be enclosed in a triangle.

Q: Can a wire be enclosed in a circle? You can't form a triangle, right? I don't think it's right, in fact, it can encircle a circle, or it can enclose a triangle, these can be done, for example, like a hanger, in fact, it is a triangular shape.

The city is too big, and the siege will be a long, long wire? Iron wire can be used to form a circle, can also be enclosed into a triangle, can also be enclosed into a variety of other shapes. Your statement is not true.

No, the wire can be enclosed in any shape.

This proposition is incorrect, if a wire can be enclosed in a circle, it must also be enclosed in a triangle.

Yes, a wire is changeable, and any shape can be enclosed.

A wire can be enclosed into a triangle, and the top and corners of the triangle are all connected, so it can be enclosed.

No, wires can be used to create a variety of shapes.

It depends on what kind of Tencel, if it is a soft wire, it can be enclosed into a triangle.

Four identical sticks can besiege both a square and a rectangle, right? Why?

Yes, four sticks of the same length can be enclosed either in a square or in a rectangle. The reason for this is as follows: when four sticks of the same length are arranged in a square, the angle between each two swift grinding sticks is 90 degrees.

Each stick becomes one side of a square, all of equal length. However, when the four sticks are arranged in a rectangle: in order to ensure that the sticks are of equal length, the two longer sticks (i.e. the diagonal lines of the square) need to be placed next to each other to form a right-angled triangle.

This, four wooden sticks together form a rectangle. Another way to form a rectangle is to bend four sticks of the same length so that the ends of each stick are attached to the other two sticks. With proper angle adjustment, four sticks can be arranged in a rectangle, where two equal parts of each stick.

So, four sticks of the same length can indeed enclose both a square and a rectangle. It depends on how the sticks are arranged and connected to each other.

12 3 4 = 9 cm.

9 centimeters = decimeters.

The side length of the square is decimeter.

Also 4a long. Punching fingers.

Square area a 2

Circle area (2a)2* =4a2 >a2

Let the length of the wire be x cm.

x/3-x/4=5

x/12=5

x=5x12

x = 60 cm.
