You need to determine whether the triangles are congruent by ASA, SSS, SAS, AAS or HL. Then you can say that the triangles are congruent; after that, you need to go back to what the were asking you to prove, for example, if they were asking you to confirm that AC and GD were congruent, state that they are congruent and then put CPCTC as a reason. Am I making sense?

serg [7]
X=number of books that cost 0.60
y=number of books that cost 0.75

x+y=16
0.6x+0.75y=10.95

solve
multiply second equation by 10 for nicity
6x+7.5y=109.5

multiply first equesiotn by -6 and add to second

-6x-6y=-96
<u>6x+7.5y=109.5 +</u>
0x+1.5y=13.5

1.5y=13.5
divide both sides by 1.5
y=9

sub back
x+y=16
x+9=16
minus 6
x=7
