G-SRT-10: … use them <Laws of Sines and Cosines> to solve problems.
G-SRT.11: apply the Law of Sines and the Law of Cosines
to find unknown measurements in right and non-right triangles (e.g.,
surveying problems, resultant forces).It looks like the entirety of SRT.11 fits into SRT.10. What kind of problems are envisioned for SRT.10 that are different from finding unknown measurements in triangles? Even the first parts are hard to separate. Depending on the point of view, “understanding” (SRT.11) includes being able to prove (SRT.10).
Any clarification on these two will be greatly appreciated.
Well, it’s a bit like saying “Get ready for school, and don’t forget to brush your teeth.” Brushing your teeth is implied by getting read for school, but you want to make sure it isn’t forgotten. G-SRT.11 is a brush-your-teeth standard. Same goes for calling out proof in G-SRT.10 … you want to make sure people see that.
