8-23.

Graph these points on a coordinate grid and connect them to make a triangle: , , . Then:

  • Dilate the shape by multiplying each coordinate by .

  • List the coordinates of the new vertices.

What do you notice about the sides of the two shapes?  

Look at the graph to find the coordinates of the new vertices. What do you notice about the sides of the triangles?

All pairs of corresponding sides are parallel.
