Instructions.
Use the scale factor slider at the top to vary the scale factor from
\(0\) to
\(4\text{.}\) Observe how the enlarged triangle changes size relative to the original. You can also click and drag the center of enlargement (point
\(O\)) or any of the vertices on the original triangle (
\(A\text{,}\) \(B\text{,}\) and
\(C\)) to explore how the transformation responds.
