I need a explanation of how to solve the following:
1. Prove triangles congruency in 2-column style : SSS,SAS,ASA.
2. Use trig functions (sine, cosine, tangent) and inverse trig functions (sin<sup>1</sup>, cos<sup>1</sup>, tan<sup>1</sup>) to find missing information.
3. Use the Law of Sines to find the missing oieces of non-right triangles.
4. Determine whether shapes are similar using the properties of similarity (AAA, correspoding sides have equal ratios).
5. r:r2:r3
6. Find the sum of interior angles of a polygon: (n - 2)(180°)
7. Find the volume of prisms and pyramids (Bh, Bh/3)
8. Total surface area of 3-dimensional figures giving base, height, and slant height measurements.
Thanks for reading and help is greatly appreciated! =]
