USAMTS Round 3 - Art of Problem Solving
... by being an angle of a regular pentagon, angles A2A1A3 and A2A3A1 are equal to (180 - 108) / 2 = 36 degrees. Since angle A4A3A2 is equal to 108 degrees and angle A2A3A1 is equal to 36 degrees, angle A4A3A1 is equal to 108 - 36 = 72 degrees. Next, since congruent angles B1 B2 B3 B4 B5 add up to 180 d ...

... to be given in lessons nine and ten as well as a four A4 page pamphlet and an A3 poster in lesson eleven. Projects are: (A) why are pylons made from triangles? (B) using the sin and cos ratios (as well as tan); (C) triangle numbers (D) how can we construct a triangle given three sides and a compass? ...
