## Construction of Triangles

A Triangle can be constructed when at least three parts of the triangle are given. But all the combinations of three parts are not sufficient for the purpose. For example, it is not possible to construct a unique triangle when the measurements of two sides and an angle that is not included in between the given sides are given.

A triangle can be constructed when:

1. The base, one base angle, and the sum of the other two sides are given.
2. The base, a base angle, and the difference between the other two sides are given.
3. Perimeter and two base angles are given.
