Triangle shape: Triangles are fundamental in

Triangles are fundamental in Euclidean geometry, and their properties are essential for various real-world applications. The triangle shape is one of the most common shapes that we observe in our daily lives. We observe traffic signals, snacks, cloth hangers, etc. which are shaped like triangles . A triangle is a fundamental geometric shape composed of three-line segments that intersect at three distinct points. This article aims to cover the definition, types, properties, formulas for calculating area & perimeter, and examples of triangles . Triangle A triangle is a 3-sided polygon. 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 . Parts of a triangle The following list describes various common parts of a triangle : Side - A side (or edges or leg) of a triangle is one of the three line segments that form the triangle . Vertex ... Triangles are three-sided polygons with 3 sides, 3 vertices, and 3 internal angles. We denote a triangle as ABC (or whichever three letters represent its vertices).
