Dilations: Finding Scale Factor, and Dimensional Changes
7. Triangle ABC has vertices A(1, 4), B(1, 5), and C(1, 4). The triangle is dilated with a scale factor of 3, and the dilation will be centered at the origin. Write an algebraic representation for the dilation. Determine the coordinates of the image of point A after the dilation.

Now, drag the unit point at (1,0) to the right to increase the unit size of the graph until the vertices of the triangle are spread a little more. Using the line tool, , connect each of the vertices to create the triangle as shown at the right. Construct each of the common center’s of the triangle (Centroid, Incenter, Circumcenter, Orthocenter).

The area of the polygon is n times the area of each triangle (there are n triangles). So the area of the polygon is . But is the perimeter of the polygon. So the area of the polygon can be written. EX: Find the area of a decagon with a 12in apothem and 8in sides. EX: Find the area of an equilateral triangle …

To do this, subtract the coordinates of the center of the triangle from the coordinates of each of the stations. The transformed coordinates of the three stations are as follows: station 146 : {(712245.8 - 738872.9), (4357118.8 - 4366047.1)} = {-26627.1, -8928.3}

Move the vertices of your triangle (or endpoints of your segment) to check that the two points remain coincident. Notice that all of your measured and calculated coordinates change as you move the points. In Figure 3.5, point G is the constructed midpoint of segment AB. Figure 3.5: A Triangle and its Coordinates
