Book Free DemoA triangle has three sides, three vertices, and three angles. A triangle with vertices \(A\), \(B\), and \(C\) is denoted as \(△ABC\).
Properties of a triangle:
The first property of a triangle: The sum of the three interior angles of a triangle is always \(180°\).
\(∠A + ∠B + ∠C = 180°\).
The second property of a triangle: The sum of the length of two sides of a triangle is always greater than the length of the third side of a triangle.
\(AB + BC > AC\) or \(BC + AC > AB\) or \(AB+ AC > BC\).
