1. Drawing Dilations

2. Enlargements Scale Factor: 3/2
Eyeball check: are the sides of the enlargement parallel to the sides of the original?
Enlargements
8 x 3/2 = 12
6 x 3/2 = 9
8cm
10 x 3/2 = 15
6cm
10cm
4. Repeat steps 2 and 3
for the remaining vertices.
Then connect the points.
3. Measure the new distance from
The center along the extended line
And mark it with a point.
2.Measure the distance from the
The center to a Vertex.
Then multiply
It by the scale factor.
1. Draw rays from the center
extending through each vertex
Scale Factor: 3/2

3. Reductions Scale Factor: 2/3 10.5cm
Eyeball check: are the sides of the enlargement parallel to the sides of the original?
10.5cm
10.5 x 2/3 = 7cm
7.5 cm
7.5 x 2/3 = 5cm
12 x 2/3 = 8cm
12 cm
9cm
9 x 2/3 = 6cm
4. Repeat steps 2 and 3
for the remaining vertices.
Then connect the points.
3. Measure the new distance from
The center along the segment
And mark it with a point.
2.Measure the distance from the
The center to a Vertex.
Then multiply
It by the scale factor.
Draw segments from the
Center to each vertex
Scale Factor: 2/3

4. Steps Draw segment or ray from center to or through a vertex.
Measure from center to vertex.
Multiply the measure by the given scale factor.
Measure FROM the center toward or through the vertex to find the corresponding vertex.
Repeat for each vertex.
Connect in order and do a parallel check.
