Triangles - Equilateral, Isosceles and Scalene - Math is Fun
WEBA 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:

Triangles in Geometry (Definition, Shape, Types, Properties
WEBIn 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.
Triangle - Wikipedia
WEBA 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.

WEBTriangles are polygons (shapes) with three sides and three angles, which can be formed by connecting any three points in a plane. They are one of the first shapes studied in geometry. Triangles are particularly important because arbitrary polygons (with 4, 5, 6, or ...
Classifying triangles (video) | Khan Academy
WEBAbout. Transcript. The video explores how triangles are classified based on their sides and angles. It introduces the terms scalene, isosceles, and equilateral for side lengths, and acute, right, and obtuse for angles. It emphasizes that triangles can be categorized in multiple ways based on these characteristics. Created by Sal Khan. Questions.

WEBA 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:
