A polygon is a closed figure bounded by sides. A triangle is a closed figure bounded by three sides. Therefore, according to the definition of polygon triangle is a polygon.
No. A triangle may have a 90-degree angle, but not all triangles do. The only requirement for being called a triangle is that it is a closed figure with 3 sides.No. A triangle may have a 90-degree angle, but not all triangles do.

A triangle is a geometric figure that is made of three line segments. It is a closed figure and has three angles.
A close figure is a figure with no open spaces in it and is completely closed. Examples are: quadrilateral square rhombus parallelogram quadrangle rhomboid rectangle oblong kite trapezium trapezoid
An equilateral triangle has three equal sides1. 1. Any triangle has only three sides. A triangle is a closed figure that is bounded by three straight lines.
Starting with the definition of polygon makes much easier to understand why triangle is a polygon.Definition: A polygon is a closed figure bounded by sides.Definition of triangle: Triangle is a closed figure bounded by three sides.Since triangle is also a closed figure bounded by sides therefore, triangle is a polygon.
closed figure
A polygon is a closed figure bounded by sides. A triangle is a closed figure bounded by three sides. Therefore, according to the definition of polygon triangle is a polygon.
no.
yes
yes
an open figure is a polygon that is not completely closed.
Closed
If the start and end points of a figure are same, then it is called a closed figure. Examples can be a square or a triangle or a pentagon.
Triangle
A triangle.
A three sided closed plane figure (shape) is a triangle.
