Question

Olympic Games are held every four years. They were last held in 2016 in Rio de Janeiro (Brazil). When will the next three games be held? Are these years leap years?​

Answer 1

Step-by-step explanation:

XY and X′Y′ are two parallel tangents to a circle with centre O and another tangent AB with point of contact C intersecting XY at A and X′Y′ at B.

Construction :- Join OA, OB, OX, OX' and OC

Now, In ∆ XOA and ∆ COA

∠OXA = ∠OCA [ Radius is perpendicular to tangent ]

OA = OA [ Common ]

OC = OX [ Radii ]

⇛∆ XAO ≅∆ CAO [ By RHS Congruency Rule ]

∴∠1 = ∠2 [ CPCT ]

Answer 2

Despite all of these troubles, the Rio Games started on time and there were few significant problems over the course of the two weeks. The Games featured a new-record 205 participating national Olympic committees, with over 11,000 athletes competing in 42 sports.
