Non-examples of Triangles. The above figures are non-examples of triangles. These shapes cannot be called triangles as – The first figure is four-sided. The second figure is an open shape. The third figure has a curved side. Parts of a Triangle. A triangle has 3 sides. In triangle ABC, the sides are AB, BC, and CA.
Regular Polygons – Polygons that have equal sides and angles are regular polygons. For example, an equilateral triangle is a three-sided regular polygon. A square is a four-sided regular polygon. A Regular hexagon is a six-sided regular polygon. Here are a few examples of regular polygons.
- A diagonal of a polygon is a line segment connecting two non-consecutive vertices (corners).
- A Regular polygon has all sides of equal length and each angle also measures equal.
- Polygon is a closed shape made up of straight-line segments. The circle is a closed figure but it is made of a curve. So, a circle is not a polygon.
- A polygon must have a minimum of three sides.
- No, polygons have the same number of sides and angles because they are closed figures with non-intersecting lines.
Sep 19, 2024 · Triangles Definition. Triangles are polygons with three sides. The word “Tri” means three and therefore a figure with 3 angles is a triangle. It is formed with the help of three-line segments intersecting each other, a triangle has 3 vertices, 3 edges, and 3 angles. It is a 2-dimensional polygon in Euclidean geometry.

Triangles. In Geometry, a triangle is a three-sided polygon that consists of three edges and three vertices. The most important property of a triangle is that the sum of the internal angles of a triangle is equal to 180 degrees. This property is called angle sum property of triangle.

An example of a polygon is a triangle with three sides. A circle is also a plane figure but it is not considered a polygon, because it is a curved shape and does not have sides or angles. Therefore, we can say, all the polygons are 2d shapes but not all the two-dimensional figures are polygons.

For example, a 3-sided polygon is a triangle, a 4-sided polygon is a quadrilateral, a 5-sided polygon is a pentagon, a 6-sided polygon is a hexagon, and so on. Polygon Chart The following chart shows the naming convention of polygons on the basis of the number of sides that they have.

Triangle definition. A triangle is a closed, two-dimensional shape that has 3 sides, 3 angles, and 3 vertices. It is the polygon with the fewest sides. Since it is the simplest form of a polygon, any polygon can be constructed using two or more triangles.
