What is Meant by Triangle?
In mathematics, the triangle is a closed two-dimensional plane figure. It is a polygon with three sides and three angles. The sum of the interior angles of the triangle is equal to 180 degrees. Based on the measurements of angles and sides, the triangle can be classified into different types. Based on the sides, the classification of triangles is:
- Scalene triangle
- Isosceles triangle
- Equilateral triangle
Based on the angles, the classification of triangles is:
- Acute angle triangle
- Obtuse angle triangle
- Right angle triangle
The formula to calculate the area and the perimeter of a triangle is given below:
Area of triangle, A = (½) bh square units
The perimeter of a triangle, P = a + b+ c units
Where
a, b, c are the sides of a triangle
b is the base
h is the height
