... Proof: We set up correspondence ACD ↔ BDC and show it is a D congruence. Side DC in one triangle corresponds to side CD in the other, and these are congruent. ∠ADC and ∠BCD correspond and are congruent since both are right angles. Finally, side AD in one triangle corresponds to side BC in the other, ...

... one point x ∈ F such that (x + V̄ ) ∩ A 6= ∅ for all A ∈ G. But by the maximality of G, this implies that x + V ∈ G. This, in turn, implies that (x + V̄ ) − (x + V̄ ) ⊂ V̄ − V̄ ⊂ W . hence, G is Cauchy. Since E is complete, G converges to a point of E. Since the sets in G are closed, this point must ...

... Polygons can be classified as concave and convex. Convex Polygon: A convex polygon is defined as a polygon with all its interior angles less than 180°. This means that all the vertices of the polygon will point outwards, away from the interior of the shape. Think of it as a 'bulging' polygon. Note t ...
