Math Problem Statement

Plot the image of Figure ABCDEFGHIJKL after a dilation with scale factor 1/2. One of the sides has been plotted for you.

Solution

To solve the problem of dilating the figure ABCDEFGHIJKLABCDEFGHIJKL by a scale factor of 12\frac{1}{2}, you need to reduce each coordinate of the vertices to half its distance from the origin (or the center of dilation if specified).

Steps to Solve the Dilation

  1. Identify Coordinates: Locate the coordinates of each vertex A,B,C,,LA, B, C, \dots, L on the grid.
  2. Apply the Scale Factor: Multiply each coordinate by 12\frac{1}{2}. For example:
    • If a vertex is at (x,y)(x, y), the new coordinates will be (x2,y2)\left( \frac{x}{2}, \frac{y}{2} \right).
  3. Plot the New Points: Place the new points on the grid and connect them in the same order as the original figure.

Partial Solution Insight

In the image, the segment KLK'L' has already been plotted after applying the scale factor 12\frac{1}{2}. The other points of the figure need to follow the same procedure.

Tip:

To ensure accuracy, always start with plotting key vertices first (e.g., AA and BB) and use symmetry or shape consistency for faster construction.
