Solution of moving a match coin out of the room

The moving method of this puzzle game is as follows:

First, the rules are as follows: form an equilateral triangle with three matches, and then put a coin in it. At this time, it is required to move a match so that the coin is outside the triangle, and the match can still form a triangle.

Second, the moving method, as shown below, moves the green one to the upper position here.

Third, the effect after moving is as follows. At this time, the three matches are still a triangle, but the coins have already run outside the triangle.
