• Architects, graphic designers, and engineers who apply dilation in their work.
  • When a figure is dilated, its size changes, but the shape remains the same. Imagine a circle with a radius of 5 cm; if it's dilated by a scale factor of 3, the new radius will be 15 cm, and the circle will be much larger. However, the ratio of the radius to the diameter, a fundamental property of a circle, remains unchanged. The process of dilation involves understanding the concept of ratios and similarities between shapes.

    Why Dilation is Gaining Attention in the US

  • Practicing with various shapes and examples helps to reinforce understanding of dilation concepts.
    1. Architecture and Interior Design: To ensure that buildings and structures meet safety and functionality requirements, architects use dilation to design new buildings by scaling up or down existing plans.
    2. Dilation is a transformation that changes the size of a figure by a certain scale factor. It involves increasing or decreasing the dimensions of a shape while keeping its proportions the same. Imagine taking a rubber band and stretching it to double its size; the shape remains the same, but the dimensions change. Dilation can be applied to any shape, including squares, circles, and triangles.

      During dilation, the center of the shape remains unchanged, as it is the central point around which the shape is dilated.

      Shape similarity is the concept of two or more shapes that have the same proportions, whether they are dilated or not.

    3. Use these measurements to create a dilation with the scale factor.
