Answer:
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
Step-by-step explanation:
a flat geometric figure that has three sides and three angles. 2 : something that has three sides and three angles a triangle of land. 3 : a musical instrument made of a steel rod bent in the shape of a triangle with one open angle.
triangle has three sides, three vertices, and three angles. The sum of the three interior angles of a triangle is always 180°. The sum of the length of two sides of a triangle is always greater than the length of the third side. ... The area of a triangle is equal to half of the product of its base and height.
