Math Problem Statement

Dilate ABCD with a scale factor of 2 and center (0, 0). Use the Polygon Tool to plot the image.

Solution

To solve this problem, let's go through the dilation process.

Problem Breakdown:

  • Original Figure: ABCD
  • Scale Factor: 2
  • Center of Dilation: (0, 0)

Steps to Dilate the Figure:

  1. Identify the coordinates of the original vertices of quadrilateral ABCD.

    • Let's denote the vertices as A(x1,y1)A(x_1, y_1), B(x2,y2)B(x_2, y_2), C(x3,y3)C(x_3, y_3), and D(x4,y4)D(x_4, y_4).
    • From the image:
      • A(3,1)A(-3, 1)
      • B(1,3)B(-1, 3)
      • C(1,3)C(1, 3)
      • D(3,1)D(3, 1)
  2. Apply the scale factor of 2 to each vertex, using the formula: (x,y)=(kx,ky)(x', y') = (k \cdot x, k \cdot y) where kk is the scale factor (which is 2 in this case).

    So, the new coordinates will be:

    • A(6,2)A'(-6, 2)
    • B(2,6)B'(-2, 6)
    • C(2,6)C'(2, 6)
    • D(6,2)D'(6, 2)
  3. Plot the new coordinates A,B,C,DA', B', C', D' on the graph to form the dilated quadrilateral.

Would you like to proceed with additional details on this process or have any specific questions about it?


Relative Questions:

  1. What is the general formula for dilating a point with respect to a different center of dilation?
  2. How would the shape change if the scale factor was less than 1?
  3. What happens to the area of the quadrilateral after dilation with a scale factor of 2?
  4. How would the coordinates change if the dilation were centered at a different point, say (1,1)?
  5. Can you identify any properties of the quadrilateral that remain unchanged after dilation?

Tip:

Always double-check the new coordinates after applying the scale factor to ensure accuracy in geometric transformations.
