The correct answers are:
A. SSS
; C. ASA
; D. SAA
; E. SSA
; and F. SAS
Explanation:
The Law of Cosines is used when we have at least two sides. This is because the law of cosines is
\(c^2=a^2+b^2-2ab\cos{C}\)
This means SSS, SAS or SSA triangles can use the law of cosines.
For other triangles, we can use the Law of Sines (having two angles): ASA or SAA (also known as AAS). This is because the law of sines is
\(\frac{a}{\sin{A}}=\frac{b}{\sin{B}}=\frac{c}{\sin{C}}\)
