Calculate the distance using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (1, 0) and (x₂, y₂ ) = (0, 2)
d =

The rotation of the triangle ABC 360 degrees about the y-axis forms a cone
<h3>How to determine the shape after rotation?</h3>
From the question, we understand that the triangle ABC is a right triangle
The vertical cross-section of a cone is a right triangle.
This means that a right triangle can be rotated 360 degrees on one of its legs (opposite or adjacent) to form a cone
Hence, the rotation of the triangle ABC forms a cone
