No 3D shape with FLAT SIDES has exactly 3 faces. 4 is the minimum.
a triangle anything with 3 sides is a triangle
A shape with four sides has four vertices and a shape with three sides has three vertices, so a shape with four sides has more vertices than a shape with three sides.

a triangle anything with 3 sides is a triangle
A shape with 3 sides is exactly triangular as for example an equilateral triangle has 3 equal sides and 3 equal angles of 60 degrees that add up to 180 degrees.
Assuming that each vertex is used to connect exactly two sides, all two-dimensional shapes will have the same number of sides as vertices. So a shape with 4 sides will have 4 vertices and a shape with 3 sides will have 3 vertices. Think of a square (4 sides, 4 vertices) and a triangle (3 sides, 3 vertices).
Yes, a polygon has 3 or more sides, but to be specific a pentagon is the shape that has exactly 5 sides.
For example, one that has 3 sides (a triangle), one that has 5 sides (a pentagon), etc.
An isosceles triangle has exactly one line of symmetry.
There is no shape that is made up 3 sides that is not a triangle. Any shape that is made up of 3 sides is classified as a triangle no matter what shape or size it is.
A triangle as no other 2d shape can have 3 sides.
