### What is Meant by the Side Angle Side?

In Geometry, a triangle is a closed two-dimensional figure with three sides and three vertices. The triangle can be classified into many types based on the sides and angles. Based on the sides, the classification of different triangles is a scalene triangle, isosceles triangle, and equilateral triangle. Based on the angles, the different types of triangle classifications are acute triangle, obtuse triangle and a right triangle. We know that the area of a triangle is the region occupied by the triangle. We can find the area of a triangle in different ways. In case, if the two sides of a triangle and an angle are given, the area of a triangle is calculated as follows:

Area of a triangle = (a × b × sin C)/2 square units.

Where “a” and “b” are the sides

“C” is an angle

For example,

If the two sides of a triangle are 4 and 5 cm, and the angle is 30°, then the area of a triangle is,

Area of a triangle = (a × b × sin C)/2 square units

A = (4 × 5 × sin 30)/2

A = [20×(1/2)]/2

A = 10/2

A = 5 cm^{2}

Therefore, the area of a triangle is 5 square units.
