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.
Triangles - Equilateral, Isosceles and Scalene. 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?

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.
Aug 24, 2023 · Key takeaways. A triangle is one of the most important shapes in mathematics – Learning about triangles builds the foundation for more challenging subjects like geometry and trigonometry. There are different types of triangles – You can label a triangle by the size of its angles, the size of its sides, or both!
