After Tasha moves A to A′, A′ is 2​ units to the right of A and 3​ units above O. Therefore, A′=(sqrt2​,sqrt3​).

After Richard moves A′ to A′′, A′′ is 90∘ clockwise from A′ and the same distance from O. Therefore, A′′=(−sqrt3​,sqrt2​).

After Richard moves A to A1​, A1​ is 90∘ clockwise from A and the same distance from O. Therefore, A1​=(−sqrt3​,sqrt3​).

After Tasha moves A1​ to A2​, A2​ is 2​ units to the right of A1​ and 3​ units above O. Therefore, A2​=(−sqrt3​+sqrst2​,sqrt3​+sqrt2​).

Therefore, A′′A2​=(−sqrt3​+sqrt2​−(−sqrt3​))(−sqrt3​+sqrt2​−sqrt3​+sqrt2​) = sqrt(2)​.
