4 Identical Triangles - solution

[Tap_521]

Umm... question if you do 4 identical triangles shouldn't you have 4 acutal triangles not a 4 then a picture a of triangle. Could you explain how this is (what you showed me) the correct answer and how it is logic promblem and not just a math joke.

it's impossible to get 4 actual triangles with the current setup, so the only way to get 4 is to actually make a 4.

How about a diamond with a cross in the center?

yes that would be 4 triangle but the current arrangement of the triangle doesn't allow the formation of the diamond.

Site Admin,
I don't really understand your solution, could you please explain it?

[rookie1ja]

it's just a little joke ... child's play ... you create number "4" from the first triangle and keep the second triangle thus it could be 4 triangle

try a 3D figure n u'll find the solution

Umm, not a logic puzzle, however it is possible to move one matchstick and get 4 triangles; just not 4 identical

Solution process: Hmm... This is pointless, but... Lost my idea. I'm going insane! Maybe... I'll look at the solution! Hahaha... what a nice joke.
