How many triangles dose an 18 gon have?

Answer 1

An 18-gon, also known as an octadecagon, has 18 sides. To find the number of triangles in an n-gon, you can use the formula (n-2)C3, where C represents a combination. Plugging in n=18, we get (18-2)C3 = 16C3 = 16! / (3!(16-3)!) = 16! / (3! * 13!) = 161514 / 321 = 560. Therefore, an 18-gon has 560 triangles.

Answer 2

An 18-gon has 1,458 triangles. Yep, you heard me right, 1,458! So, get ready to count those triangles if you want to prove me wrong, honey!

Answer 3

560
