How to swing at most a few corners with two small sticks

Two small sticks can create up to 4 corners.

Here the angles are in geometry.

refers to a geometric object consisting of two rays with a common endpoint.

Answer: 4, such as the right angle of the fork. "As shown in the figure below. t

With two small sticks, you can have up to three corners, only to see one horizontal and one vertical.

Up to 13 corners can be posed.

Answer: You can swing 4 corners. As shown in the figure below. x

When the three small sticks intersect in pairs, 12 corners are obtained.

The intersection of two small sticks will produce 4 corners, and the intersection of three small sticks in pairs three times will give 12 corners.

When swinging, you only need to make each two of the three sticks intersect to create 12 corners.

Use at least 5 sticks for 2 triangles, at least 7 sticks for 3 triangles, and up to 5 triangles if you have 9 sticks of the same length.

Common triangles are divided into ordinary triangles (the three sides are not equal) and isosceles triangles (isosceles triangles with unequal waists and bases, and isosceles triangles with equal waists and bottoms, that is, equilateral triangles); According to the angle, there are right triangles, acute triangles, obtuse triangles, etc., of which acute triangles and obtuse triangles are collectively referred to as oblique triangles.

The stability of the triangle makes it not easy to deform like a quadrilateral, and it has the characteristics of stability, solidity, and pressure resistance. Triangular structures have a wide range of engineering applications. Many of the buildings are triangular in shape, such as the Eiffel Tower, the Egyptian pyramids, and many more.

At least 5 small sticks should be used to place 2 triangles, at least 7 small sticks should be used to place 3 triangles, and if there are nine, the plane figure can be placed up to 5; A maximum of 7 three-dimensional shapes can be posed.

It takes three sticks to place 1 triangle, and at least how many small sticks do you need to use to place 2 triangles? (Is it the same length of sticks, if yes, 5 sticks; If not, 4 roots) What about 3 roots? If you have 9 sticks of the same length, you can make up to 4 triangles.

With 16 identical sticks, you can make 4 different rectangles.

7 long, 1 wide;

6 long, 2 wide;

5 long, 3 wide;

4 long and 4 wide (squares are special rectangular).

To solve this problem, first find how many small sticks are needed for half, and 16 2=8 for half. 8=1+7=2+6=5+3=4+4

For a long time, it is wider one, six long, two wide, and three souls of Changwu Gengkun.

Summary. Pro, angle is a geometric noun, and the definition of angle is a figure consisting of two rays with a common endpoint called an angle. This common endpoint is called the vertex of the angle, and these two rays are called the two edges of the angle.

General angles are assumed to be on the Euclidean plane, but they can also be defined in non-Euclidean geometry.

Angles have a wide range of applications in geometry and trigonometry. Angles can be divided into 10 types: acute angles, right angles, obtuse angles, flat angles, circumferential angles, negative angles, positive angles, superior angles, inferior angles, and 0 angles. The system of measurement of angles in degrees, minutes, and seconds is called the angle system, and in mathematics the symbols of angles are represented by .

Hurry up, okay. Okay, dear, you wait for me for three minutes [than heart] [than heart].

Hello dear, use three small sticks to pose 12 corners as shown in the picture above<>

Can you explain that?

Okay dear, you wait a moment [than the heart] [than the heart].

Pro, because three small rods intersect, the original angle can be divided into many points, and the intersection of three rods will form four corners for each stick, so 3 4 12 <>

A right angle is an angle formed by the vertical intersection of two straight lines or two planes. Those with smaller angles than right angles are called acute angles, and those that are larger than right angles and smaller than flat angles are called obtuse angles.

The triangle has three sides, the three sides correspond to three small sticks, each two small sticks can be enclosed into a corner, and the fourth small stick is used as the middle line of the triangle, which is the line in the triangle that connects from the midpoint of one side to the vertex of the opposite diagonal, so that it can be put together into two triangles.

A triangle is a shape made up of three lines connected end to end, and the triangle is the most stable of all shapes. This property is used in many important constructions based on the stability of the triangle. For example: triangular brackets.

A closed shape consisting of three line segments that are not on the same line is connected one after the other, called a triangle. The figure enclosed by three straight lines on the plane or three arcs on the sphere, and the figure enclosed by the three straight lines is called a plane triangle; The shape enclosed by three arcs is called a spherical triangle, also known as a trilateral.

The resulting closed geometry is called a triangle when three line segments are connected end to end. A triangle is the basic shape of a geometric pattern.

In addition to using four small sticks to make two triangles, you can also use five small sticks to make a triangle, and the two triangles are congruent triangles and combine to form parallelograms.

Whether it's an obtuse triangle, a right triangle, or an acute triangle, you can make two triangles with 4 small sticks.

Use a small stick to swing five triangles with at least 15 small sticks, because if the triangle is equilateral with 3 small sticks, you can regret putting out a triangle, and the triangle is 3 5 15 (root), so at least use the remaining 15 small sticks.

By default, all sticks are the same length and all triangles are on the same plane.

Swing 2: If there is a common side, you need to:

2*3-1=5 roots.

Swing 3: one triangle has a common side with two triangles, you need:

3*3-2=7 roots.

Solution: 3 2 = 6 (root), 3 3 = 9 (root).

Answer: It takes at least 6 small sticks to place 2 such triangles, and 9 sticks to place 3 triangles.

One corner is the "L".

The two horns are the "fierce return".

The four corners are the "ten".

Formulas containing equal signs are called equations. Equations can be divided into contradictory equations and conditional equations. Add (or subtract) the same integer to both sides of the equation at the same time.

Either both sides of the equation are multiplied or divided by the same non-0 integer, or the left and right sides of the equation are multiplied at the same time, and the equation still holds. The form is to connect two equal numbers (or numbers represented by letters) with "=".

One corner is the "L".

The two corners are "丄".

The four corners are the "ten".
