Class 7 Mathemathics: Vertices are the corner points of a triangleClass 7 Mathemathics: A triangle has three angles, one at each vertexClass 7 Mathemathics: Naming a triangle is done by naming its vertices, e.g., ∆ABCClass 7 Mathemathics: If three points lie on a straight line (collinear), they do not form a triangle because the shape is not closed and has no area or angles formed inside it, only a straight line segment is formed between the points, so no triangle exists in this case. This is a fundamental property of triangles and is often tested in exams. This concept helps students understand the difference between a triangle and collinear points, which is crucial for geometry problems and proofs
