Dilation of Segments and Points

The video tutorial explains how to perform a dilation on a rectangle ABCP with center at P and a scale factor of 1 and 2/3. It details the process of calculating new positions for points A, B, and C, and completing the rectangle after dilation. The tutorial also compares the lengths of segment AB before and after dilation, demonstrating the effect of the scale factor.

• 2

What happens to point P after the dilation?

• It moves to a new position

• It becomes the midpoint of AB

• It doubles its distance from the origin

• It remains at the same position

How far is point C from P after the dilation?

• 6 units

• 8 units

• 10 units

• 12 units

What is the new x-coordinate of point A after dilation?

How does the horizontal distance of point B from P change after dilation?

• It becomes 5 units

• It becomes 4 units

• It becomes 6 units

• It remains the same

What is the new vertical distance of point B from P after dilation?

• 12 units

• 10 units

• 8 units

• Subtract the scale factor from the coordinates

What is the final conclusion about the dilation of rectangle ABCP?

• The rectangle remains unchanged

• The rectangle shrinks

• The rectangle rotates

• The rectangle expands
