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?

c)
Step-by-step explanation:
Find the LCM of 5, 6 = 30
The calculator rounded the answer.
The exact value of is , i.e. a zero followed by infinitely many 6s.
The calculator can store only 4 decimal digits, so it has to approximate the number. By doing so, it has to "choose" between 0.6666 and 0.6667.
Since the next digit is a 6, the approximation is 0.6667.
In fact, if you have to approximate with four decimal digits, you have to look at the fifth. If it is between 0 and 4, you use your fourth digit. For example, 0.35742 is approximated by 0.3574.
If instead the fifth digit is between 5 and 9, you raise the fourth digit by one: 0.57836 is approximated by 0.5784
