We did mental math and then started working on trignometry. Talked about right triangles (a^2 + b^2 = c^2) CAPITALS always mean points or verticies. lowercase always mean side length. Theta is the angle we're talking about, talked a bit about cosine, tangent & hypotenouse. Pythagorean Triples >> 3, 4, 5 5, 12,17 pythagorean triples must have 3 whole numbers. We also made a spread sheet but i duno how to do that.
