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 regular 4 sided polygon is a square. A polygon having all sides of equal length and the interior angles of equal measure is known as a regular polygon.

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.

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. The same can be said about a rectangle. In an equilateral polygon, each side has the same length. A regular polygon is BOTH equiangular and equilateral. A square is a regular polygon because all sides have the same length and all angles measure the same: 90 degrees. An obtuse triangle will always have one angle whose measure is greater than 90 degrees but at the same time less than degrees.

What a shape that look like a triangles?

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 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.

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. How many as yet unknown properties of other figures may there not be? It is common to label the vertices of a triangle in counterclockwise order as either , , or , ,.

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.

The angles and sides of a triangle also satisfy an array of other beautiful triangle inequalities. The two circles intersect at two points, and , and is the second point at which the line intersects the first circle. This is the SSS theorem.

A triangle is a closed, two-dimensional shape that has 3 sides, 3 angles, and 3 vertices.

One form of such coordinates is known as trilinear coordinates , with all coordinates having the same sign corresponding to the triangle interior , one coordinate zero corresponding to a point on a side, two coordinates zero corresponding to a vertex, and coordinates having different signs corresponding to the triangle exterior. About Us. A similar set of relations hold for Conway triangle notation , , , and. An isosceles triangle has two equal sides and one side that is not equal. For example, a triangle is a polygon with 3 sides. Previously Viewed. Jurgensen , p. In an equilateral polygon, each side has the same length. What is a three-sided shape?
