Is any 3 sided polygon a triangle

Regular polygon - A polygon having all sides of equal length and the interior angles of equal measure is known as a regular polygon i. A regular 3 sided polygon is an equilateral triangle.

A triangle is a 3-sided polygon sometimes but not very commonly called the trigon. Every triangle has three sides and three angles, some of which may be the same. The sides of a triangle are given special names in the case of a right triangle , with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs. All triangles are convex and bicentric. That portion of the plane enclosed by the triangle is called the triangle interior , while the remainder is the exterior. The study of triangles is sometimes known as triangle geometry , and is a rich area of geometry filled with beautiful results and unexpected connections. In , while studying the Brocard points of a triangle, Crelle exclaimed, "It is indeed wonderful that so simple a figure as the triangle is so inexhaustible in properties.

Is any 3 sided polygon a triangle

A polygon is a closed geometric figure whose sides are simple line segments. Each corner of a polygon where two sides intersect is called a vertex of the polygon. For example, a triangle is a polygon with 3 sides. There are also three vertices, one at each point. This is the simplest polygon, because you can't construct one with just 1 or 2 sides try it! NOTE: There are many more polygons, but the ones listed here are some of the most popular and most often taught in geometry classes. Polygons with more than 12 sides are usually referred to as n-gons. As in, a polygon with 56 sides is a gon. In an equiangular polygon , each angle has the same degree measure. A square is an example of an equiangular polygon because each of the 4 angles form 90 degrees.

Wiki User. It would technically still be a triangle but not as most people would see it a semicircle that instead of having one flat side and one curved then one curved and two pointy a bit like a normal triangle but with a curved bottom. A triangle can also be called a three sided polygon, or possibly a wedge shape. A three sided closed plane figure shape is a triangle. A 3 dimensional triangle is called a pyramid, otherwise a 2D three sided polygon shape is exactly what you called it, a triangle. A three-sided polygon is, by definition, a triangle.

Geometric shapes, also called figures, are an important part of the study of geometry. The triangle is one of the basic shapes in geometry. It is the simplest shape within a classification of shapes called polygons. All triangles have three sides and three angles, but they come in many different shapes and sizes. Triangles have some important characteristics, and understanding these characteristics allows you to apply the ideas in real-world problems. A polygon is a closed plane figure with three or more straight sides. Polygons each have a special name based on the number of sides they have. The table below shows and describes three classifications of triangles. Notice how the types of angles in the triangle are used to classify the triangle. This fact can be applied to find the measure of the third angle of a triangle, if you are given the other two.
