- - - - then multiply by the scale factor
        
        then add to the dilation point
- - - - If two triangles are similar, then their corresponding angle bisectors have the same ratio as the corresponding sides
    - - If two triangles are similar, then their corresponding altitudes have the same ratio as their corresponding sides
    - - If two triangles are similar, then their corresponding medians have the same ratio as their corresponding sides
    - - An angle bisector of a triangle divides the opposite side into two segments that have the same ratio as the other two sides
    - - Property 2 (Means or Extremes Switching Property): If a/b = c/d and is a proportion, then both d/b=c/a and a/c=b/d are proportions.
      - Property 3 (Upside-Down Property): If a/b=c/d, then b/a=d/c
      - Property 1 (Means-Extremes Property, or Cross-Products Property): If a/b = c/d, then ad=bc. Conversely, if ad = bc not equal 0, then a/b=c/d and b/a=d/c.
      - Property 4 (Denominator Addition/Subtraction Property): If a/b=c/d, then (a+b)/b=(c+d)/d or (a-b)/b=(c-d)/d
