How many equilateral triangles can six matches make

How many equilateral triangles can six matches make


Three matches are placed on the bottom to form an equilateral triangle. Then three matches are placed vertically to form four equilateral triangles. As shown in the figure below, eight equilateral triangles can be placed



How to place three equal squares with nine matchsticks?


Put it in a three-dimensional figure
First use 4 pieces to square (sit on the bottom)
And then put three on the left side of a square
Then use the remaining two to square at the back
That is, three adjacent faces of a cube



How can nine matches make three squares


First place two side-by-side square to seven can Oh, in each square in the middle of each vertical placed a match, the middle and form a square OK



How to make four triangles with six matchsticks
Match sticks are the same length


First, put three matches on the table to form an equilateral triangle, then use three matches to stand up from the three vertices of the triangle, and touch the upper ends of the three matches together to form an equilateral triangle. There are four equilateral triangles in total. You must have eaten the triangle rice dumpling. Why do you call it three



Three matchsticks can make an equilateral triangle, five matchsticks can make two equilateral triangles, can you make four equilateral triangles with six matchsticks?

Before 8:45!


Yes, it's a triangular prism with four equilateral triangles
It's a tetrahedron



How to make four equilateral triangles with six matchsticks of the same length(


Solid geometry can be realized, that is, four equilateral triangles formed by six sides of zongzi type

This is a rough picture! It's not very well drawn! It's placed at the midpoint of each match! Do you understand? The number shows you that there are four equilateral triangles!



Use six matches to make four equilateral triangles
In plane
It's not space


Three match numbers "4"
Three match pendulum triangles



How do six matches form four regular triangles?
Three matches can be placed into an equilateral triangle. How can six matches be placed into four equilateral triangles?


With space graphics,
Just form a regular tetrahedron
Three matches form an equilateral triangle,
In addition, one end of the three matches coincides with the vertex of the triangle,
The other three endpoints coincide with another point



Can six matches make four equilateral triangles?


First place a triangle, and then make one end of each of the other three matches coincide with one end of the triangle, and the other end will stand up and coincide at the same point, so that there is a triangle placed first at the bottom, and each side of the triangle will form a triangle with two of the three sides
In short, it is to build a regular tetrahedron, each side is a regular triangle
