Если угол одного треугольника равен углу другого треугольника, а стороны, образующие этот угол в одном треугольнике, пропорциональны соответствующим сторонам другого, то такие треугольники подобны. По условию (картинке) вроде так и есть.

Task 2. Read the article and answer the questions based on the reading passage. Don't forget to go back to the passage whenever
necessary to find or confirm your answers.
Competing for Resources
The resources of any one environment are limited. Depending on which plants and animals share the environment, there may
not be enough of everything to go around. All organisms need water, food and shelter to stay alive. These resources are
beneficial, which means they are good for the organisms. When an environment is low on any of these things, organisms must
compete for them. Those who get to the resources first have the best chance of survival. Being without water, food or shelter for
very long is detrimental, which means it is harmful to organisms. The resources in an area determine how big the plant and
animal populations can be. Sometimes there are too many living things in an area. The weakest of the populations will not be
able to get the resources they need. As the weak die out, the populations get smaller. Finally, the area's resources recover and
can support them again. Sometimes people will capture members of large animal populations and move them. They take them to
another location with less competition. This helps the animals survive. Sometimes the government will allow hunting of large
animal populations. Deer and rabbits can be a good food source for people. When there are too many of these animals in an area,
They sometimes come into the cities looking for food. They often cause trouble. Hunting keeps the number of animals under
control.
Answer the questions.
1) Why do organisms sometimes have to compete for resources?
2) What kinds of things are beneficial for organisms?
3) 3) What happens populations grow too large for an area?
4) Why do they sometimes come to the cities?
