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​

опольнительное построение: высоты, проведенные из точки D на основание АВ- отмечаем точку на основание как Е и из точки С на основание АВ, отмечаем эту точку как F

У нас получился прямоугольник DCFE. DC=FE=10см (потому что стороны DC и  FE противолежащие)

AB=AE+EF+FB     AE=FB (Треугольник НЕМ= треугольнику LPS по 2 признаку), следовательно FB= (24-10):2=7 см

Расмотрим треугольник ADE, угол DEA=90

Угол ADE=180-(90+60)=30

AE=1/2 AD( напротив угла 30 градусов), следовательно AD=AE*2 AD=7*2=14см

AD=CB=14см( ABCD равнобедренный)

P=DC+CB+AB+AD      P=14+14+24+10=62см

ответ: периметр трапеции 62 см.
