Explain the connections between vectors,trigonometry, and the Pythagorean theorem
+131 Pythagorean theorem is a three side triangle, sum of the areas of the othee sides ABC, Trigonometry theorem is the sum of angles, vectors theorem is the displacement. But not sure.
+874 Dunno about vectors, but in trig we have that sin^2(theta) + cos^2(theta)=1 which is like the pythog theorem
