Patricia is painting sailboats on her wall using
stencils. The stencil for the sail is a right triangle,
AABC, where m LA = 52° m m and moves the stencil 8 inches to the right. If she
paints a second sail in that spot, what will the
measures of the angles be? Let AA'B'C'
represent the second sail. What general principle
does this situation illustrate?
