Dear Betty,

    Thank you very much for your email. I know you are new here and come to Wenzhou in your car. You want to know something old in Wenzhou. You say you'd like 1 Wenzhou Museum. It is a big and famous 2. It is near Shiji Square. Let me tell you the way to it. Take your car from your hotel and 3 along Fudong Road. Turn left at the third turning, not the 4 one. You will see Wenzhou Library 5your left. The museum is opposite the library. It 6from 9:00 to 5:00pm every day, except Monday. There are lots of 7 things and paintings in the museum. I think you can enjoy yourself there.8 don't take a camera, you can't use 9 in the museum. There is a small shop next to it. You can buy some souvenirs in it. And if you have enough 10, Wenzhou Science and Technology Museum is next to it. It is a good place to have fun, too.

    I think you'll have a good time in Wenzhou!

已知曲线C₁的参数方程是$\left\{\begin{array}{c}x=2\cos \theta \\ y=2+2\sin \theta \end{array}\right.$（θ为参数），以坐标原点为极点，x轴的正半轴为极轴，建立极坐标系，曲线C₂的极坐标方程是ρ=﹣4cosθ．

（1）求曲线C₁与C₂交点的极坐标；

（2）A、B两点分别在曲线C₁与C₂上，当|AB|最大时，求△OAB的面积（O为坐标原点）．
