Yes a triangle is a 2D polygon shape
A polygon is a shape with multiple sides. For example, a triangle is a polygon with 3 sides.
A triangle in general is just a polygon. An equilateral triangle is a regular polygon.
A triangle may or may not be a regular polygon. Let's look into things.First, a triangle is a polygon. All triangles are polygons. To be a regular polygon, the polygon must have equal sides. If the triangle has sides of equal length, then that triangle is an equilateral triangle and a regular polygon. If the triangle doesn't have sides of equal length, then it isn't a regular polygon. But in any case, the triangle is a polygon.
Any shape you like - a circle, ellipse, triangle, quadrilateral, polygon with n sides, irregular shapes.

A polygon
It is the only polygon whose side lengths determine its shape.
A 3 sided polygon is the shape of a triangle.

a polygon is a connected line pretty much a shape is like a triangle
A polygon is a shape with multiple sides. For example, a triangle is a polygon with 3 sides.
You are a triangle.
A weird shape?
equilateral triangle
The only convex polygon that is rigid is a triangle.
The basic shape with 3 sides and 3 corners is called a triangle. A triangle is a polygon with three straight sides and three angles. It is the simplest polygon in Euclidean geometry.
