Answer:

A right angles triangle

Explanation:

When the coordinates given are connected together and graphed, the 3-dimensional shape that will be created is as shown in the first figure. (A right angled triangle)

If the shape is rotated about the y axis, the resulting coordinates will be;

A(0, 0), B(0, 4) and C(-2, 0)

Note that the x coordinates were the only ones that is negated. The resulting 3-D shape after reflection is also as shown in the second diagram attached below (A right angles triangle)
