Треугольник равнобедренный потому что у него все углы и стороны равны

Угол 3 = углу с 80°, угол 4 = углу 100°, следовательно угол А= углу С, а треугольник считается равнобедренным с равными углами при основании.

помогите переведите на русский языкПожалуйста-Ewan McGregor and Charley Boorman are famous British actors but they are also life-long friends.One day when they were on a motorbike ride together they had an idea.They decided to try to ride across 12 countries in just I 15 days and to film their journey for a TV programme called Long Way Round. They also wanted to raise money for UNICEF projects in the countries that they visited.
Riding their BMW GS RI 200s they crossed Europe the Ukraine Russia Kazakhstan Mongolia and Siberia. Then they flew to Alaska and travelled through Canada and the US finally finishing in New York.The journey not only tested their physical strength it also challenged their view of the world.
Ewan and Charley`s journey through Kazakhstan was not easy.The roads were sometimes difficult and the two men were very tired because they had travelled such a long way. Their cameraman Claudio fell off his bike and hurt himself badly.Their bikes got stuck in the desert sand a few times. And the average temperature was 40 c!
However the bikers didn`t give up and the Kazakhstani people helped them to stay in good spirits. At the border of Kazakhstan a big group of people were waiting to welcome them.The police showed them the way and made sure that they were safe.Many people offered the men food and drink and a bed for the night.
Ewan and Charley had the opportunity to see some of the sights of Kazakhstan. They enjoyed watching traditional Kazakh horseback games and they visited a gold mine.In his camera diary Ewan talked about the kindness of the people of Kazakhstan and said that he and Charley had had a wonderful time there.
