Here is triangle .

1. Dilate each vertex of triangle using as the center of dilation and a scale factor of 2. Draw the triangle connecting the 3 new points.
2. Dilate each vertex of triangle using as the center of dilation and a scale factor of . Draw the triangle connecting the 3 new points.

3. Measure the longest side of each of the 3 triangles. What do you notice?

4. Measure the angles of each triangle. What do you notice?

Segment measures 3 cm. Point is the center of dilation. How long is the image of after a dilation with:

1. Scale factor 5?
2. Scale factor 3.7?
3. Scale factor ?
4. Scale factor ?

Here are points and . Plot the points for each dilation described.

1. is the image of using as the center of dilation and a scale factor of 2.
2. is the image of using as the center of dilation and a scale factor of 2.
3. is the image of using as the center of dilation and a scale factor of .
4. is the image of using as the center of dilation and a scale factor of .

Make a perspective drawing. Include in your work the center of dilation, the shape you dilate, and the scale factor you use.

Triangle and triangle are scaled copies. Side measures 12 cm and is the longest side of . Side measures 8 cm and is the longest side of .

1. Triangle is a scaled copy of triangle with what scale factor?
2. Triangle is a scaled copy of triangle with what scale factor?
