Demonstration of Fractional Scaling
Loading the math board and drawing, please wait…
This example demonstrates how a fractional scaling factor affects a whole number value. Using red and blue sliders, you can set the size and scaling ratio. It involves concepts of fractions and geometric transformations, utilizing commands like Intersect, Point, Polygon, and Textfield. Suitable for middle school and above students to learn about geometric transformations and proportional relationships.
