Final answer:
Given only the facts that a triangle has a perimeter of 8 units and has interior angles x, y, and z, it's not possible to definitively classify this triangle as right, equilateral, scalene, or obtuse as more information is needed. However, some inferences can be made based on the properties of triangles.
Step-by-step explanation:
The information provided cannot definitively classify the triangle as one of the four options: equilateral, right, scalene, or obtuse. The measurements of the interior angles (x, y, z) and the perimeter of 8 units don't provide enough information. We would also need to know the lengths of the sides or additional angle measurements to classify the triangle fully.
However, we can infer some information due to some triangular properties. First, we know the interior angles of any triangle will sum up to 180 degrees, i.e, x + y + z = 180. Second, if per chance all three angles (x, y, z) are equal, then it is an equilateral triangle. If one angle is 90 degrees, it would be a right triangle. If all angle and side measurements differ, it's a scalene triangle, and if one of the angles is greater than 90, it's an obtuse triangle.
However, remember that without additional information, these assumptions can't be definitively proven. In terms of the coordinate plane, the triangle's vertices would form a triangular region within the plane but again, without side lengths or specific coordinate points, we can't get further detail.
