not me getting 18 with just pure counting

edit : idk why i wrote not me as note

23 bc in the first row you have the 3 triangles, then you have the 2 pairs of triangles, then, in the 2ⁿᵈ row you have the 3 (the first row's 3+the quadrilateral right under each triangle), then the 2 pairs of the 2ⁿᵈ's triangles as well. As you might see, there is a pattern. In the third row, like before, you add the 3 sectioned triangles, then the 2 pairs. Now, there are 4 more. For 5 more, you can just take the 1ˢᵗ, 2ⁿᵈ, and 3ʳᵈ rows, then combine the 1ˢᵗ and 2ⁿᵈ, which is 1, then the 1ˢᵗ, 2ⁿᵈ, _and_ 3ʳᵈ rows altogether, which is the last.

all the triangles in this figure will have 2 sides from the 4 verticals line and 1 from the 3 horizontal lines so
4c2 X 3c1 =18

my guy really made that so hard
A triangle is a polygon that has 3 sides no matter what shape as long as it has 3 sides Just count the total triangles

count the base it is divided in 3 write it as 1, 2, 3 add them you get 6 the count side it is divided in three just write it three then multiply 6 into 3 you will get 18 idk how r people getting 19 triangles

I looked it up on google and it said it has 25

[Peoletariatgamer]

wait hold on a second proper triangles and inpropers? because if you add inproper because inproper the answer would be 25 and also the ink is made out of carbon(sorta) which is unhealthy for the enviroment but forget that he just wanted to explain so sorry if i offendid you or anyone, still here? ok i think u want my identity so fine

Should be layers * segments! + layers = 21 since there are 3 segments. 3! Is 6, 3 * 6 =18 +3 =21

[DGZ-LEGEND]

its not possible it's more than 20

Team 21 I don’t care call me dumb all u want you will see
