The internal angles of a triangles add up to 180 degree.
If you know 2 angles, the last angle is 180 minus the 2 angles.
Did I understand the question right ?

The perimeters were all correct, but I'm not entirely sure about the areas. For a square, it is just length * Length or length squared. Rectangle is length * width. For Diameter, its the length from one side of a circle to another, which passes through the center point. And I'm not sure what you meant by the ending, Area-Triangle.
