Speaking Task 1. Choose the question from the card on the topic Entertainment and fedia^ prime prime and be ready to answer it after the teacher starts the conversation. Produce a speech by giving extended answers to the questions. Share your ideas with the class. Teacher organizes a Socratic seminar, which helps him/her to assess learners while they are speaking on the toplic Entertainment and Media and he/she prepares and cuts down questions and expressions beforehand. Learners sit in a circle and answer the question using in their speech some formal and Informal expressions to present logically connected information to their classmates. Expressions: Stating an opinion The way I see it... Sorry to interrupt, but... Is it okay if I jump in for a second? Can I add something here? Can I throw my two cents in? Not necessarily Interrupting If I might add something..... I beg to differ No, I'm not so sure about that That's for sure Expressing disagreement I'd say the exact opposite I have to side with somebody (name)on this one I was just going to say that In my opinion Expressing agreement If you ask me.. That's exactly how I feel As far as I'm concerned. If you want my honest opinion..... You have a point there That's not always the case​

АВ=ВС, т.к. треугольник равнобедренный, а АС - основание. 
ВК=2, АК=8, тогда, АВ=10.
Центр вписанной окружности лежит в точке пересечения биссектрис треугольника, проведём биссектрису ВН: точка Н совпадёт с точкой касания окружности на стороне АС, т.к. в биссектриса, проведённая из угла В, является и высотой, и медианой, т.е. угол АНС = 90 градусов. 
АН=АК, т.к. отрезки касательных, проведённых из одной точки, равны, т.е. АН=8, тогда АС=16. 
В прямоугольном треугольнике АВН АВ=10, АН=8, тогда по теореме Пифагора ВН=6. 
Найдём площадь треугольника: 1/2 * АС * ВН = 1/2 * 16 * 6 = 42.
