To find the number of triangles that can be formed in an 18-gon, you can use the formula for combinations: ( C(n, k) ), where ( n ) is the number of vertices and ( k ) is the number of vertices needed to form a triangle (which is 3). For an 18-gon, this is calculated as ( C(18, 3) = \frac{18!}{3!(18-3)!} = \frac{18 \times 17 \times 16}{3 \times 2 \times 1} = 816 ). Therefore, there are 816 triangles that can be formed from the vertices of an 18-gon.
A parallelogram can be divided into two triangles by drawing a diagonal. Conversely, two triangles can be combined to form a parallelogram. Therefore, the number of distinct parallelograms that can be formed from triangles depends on the number of triangles available and how they are arranged, but at least two triangles are needed to create one parallelogram.
A man who has something to do with triangles could be a geometry teacher, a musician in an orchestra, of a road sign maker. You may also be thinking of Pythagoras who invented the pythagorean theorum (A^2+B^2=C^2).
Infinitely many. Having found one triangle, you can find infinitely many similar triangles.

Triangles may be right triangles equilateral triangles acute or obtuse triangles
Yes all equilateral triangles are acute triangles, but not all acute triangle are equilateral triangles.
Triangles without right angles are:- Scalene triangles Obtuse triangles Isosceles triangles Equilateral triangles
there are 27 triangles in a triangle
Triangles are equilateral triangles only when all of their 3 sides are equal in lengths.
