... vertical angles, and the theorem for interior angles on the same side of the transversal follows by applying linear pairs. Alternatively, we can prove alternate interior angles are congruent by a transformational argument. Locate the midpoint on the transversal between the two points of intersec ...

... A1. Problems A, B and C were posed in a mathematical contest. 25 competitors solved at least one of the three. Amongst those who did not solve A, twice as many solved B as C. The number solving only A was one more than the number solving A and at least one other. The number solving just A equalled t ...
