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.
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. The triangle's interior is a two-dimensional region.
A triangle is a closed shape with 3 angles, 3 sides, and 3 vertices. A triangle with three vertices P, Q, and R is represented as PQR. The most commonly seen examples of triangles are the signboards and sandwiches that are in the shape of a triangle.

Triangle Definition. In Geometry, the shapes are generally classified as 2D shapes and 3D shapes. The shapes with two measures such as length and height are called two-dimensional shapes, whereas the shapes with three measures such as length, height and width are called three-dimensional shapes.
A triangle has three sides and three angles. The three angles always add to 180°. 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: How to remember? Alphabetically they go 3, 2, none:

Definition: A triangle is essentially a polygon with 3 sides. From the figure we can see that a triangle has 3 vertices and 3 edges. In our daily life we come across various triangular objects such as a clothes hanger, a pizza slice, sandwich and so on. We use the ‘\ ( \triangle\)’ symbol to represent a triangle.

The sum of all the angles of a triangle is equal to 180°. The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
A triangle is a polygon with 3 sides, 3 angles, 3 vertices. The lengths of the sides of a triangle correspond to the measures of their angles; the larger the angle, the larger the side; the smaller the angle, the smaller the side.
