A triangle is a 2-dimensional geometrical shape that is formed when three non-collinear points are joined by three line segments called sides. It is a closed figure that has three angles, three vertices, and three sides.

Types of Triangles:
1. Equilateral Triangle: A triangle that has all its sides and angles equal.
2. Isosceles Triangle: A triangle that has two sides and two angles equal.
3. Scalene Triangle: A triangle that has all its sides and angles unequal.
4. Right-angle Triangle: A triangle that has one angle measuring 90 degrees (right angle).

Properties of a Triangle:
1. Sum of all angles in a triangle is always 180 degrees.
2. The longest side of a triangle is always opposite to the largest angle.
3. In an equilateral triangle, all sides are equal and all angles are 60 degrees.
4. In an isosceles triangle, the two equal sides are opposite to the same angle.
5. In a right-angle triangle, the hypotenuse is always opposite to the right angle and is the longest side of the triangle.

Uses of Triangles:
1. Triangles are used in construction, architecture, engineering, and other technical fields.
2. Triangles can be used to determine the height of an object or the length of a distance.
3. Triangles can be used to find the area of a flat surface.
4. Triangles can represent stability and strength in various art forms.
5. Triangles are used in trigonometry to determine the angles and sides of a triangle.
