4 Constructions of Triangles

To construct a triangle, if following information is given.
• Base, an angle adjacent to the base and sum of lengths of two remaining sides.
• Base, an angle adjacent to the base and difference of lengths of remaining two sides.
• Perimeter and angles adjacent to the base.
