A triangle is a polygon with three corners and three sides, one of the basic shapes in geometry. The corners, also called vertices, are zero- dimensional points while the sides connecting them, also called edges, are one-dimensional line segments.

To classify triangles according to both angles and sides, we measure the interior angles and length of the sides of the triangle. Triangles classified based on both angles and sides are –. Area of a Triangle. The area of a triangle is the region that the triangle occupies in 2d space. The area of different triangles differs based on their size.

Equilateral, Isosceles and Scalene There are three special names given to triangles that tell how many sides (or angles) are equal. There can be 3, 2 or no equal sides/angles:

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.

Triangles can be classified into different types of triangles based on the length of the sides and the measure of the angles. Let us learn more about the properties of triangles along with the theorems based on them. What are the Properties of Triangles?

A triangle is a closed shape with 3 angles, 3 sides, and 3 vertices. A triangle with three vertices says P, Q, and R is represented as PQR. It is also termed a three-sided polygon or trigon. Learn more about triangles, types of triangles, formulas of triangles with Cuemath.

A triangle can only be formed when the sum of any two sides of the triangle is greater than its third side; if the sum of the two sides is shorter than the third, they will never meet to form a polygon; if the sum of the two sides is equal to the third, they will overlap and form a line.

In this article, let us discuss in detail the definition, types and properties of one of the two-dimensional shapes called “Triangle”. A triangle is a polygon with three sides having three vertices. The angle formed inside the triangle is equal to 180 degrees. It means that the sum of the interior angles of a triangle is equal to 180°.
