Scaling a shape in two directions
- Sybilla Beckmann
What will happen to the mushroom/tree when you change the distance between the horizontal or vertical grid lines, or both?
1) Drag the horizontal slider to change the distance between the vertical lines. Drag the vertical slider to change the distance between the horizontal lines. What do you notice? 2) When is the new shape mathematically similar to the original shape? 3) As you drag one of the sliders only, what do you notice about the angles in the mushroom/tree? 4) As you drag both sliders, when are the angles in the new mushroom/tree the same as the angles in the original mushroom/tree?
