In this unit, you learned about three acceptable criteria for identifying congruent triangles: angle-side-angle (ASA), side-angle-side (SAS), and side-side-side (SSS). In each of the following, Tell if the triangles are congruent. If the triangles are congruent, state the Postulate or Theorem that verifies it. If not, write NONE. Each question is worth 0.5 Points.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
