Almost 30% of people in Britain are unable to afford even a week's annual holiday, according to an analysis by the Office for National Statistics, which reveals the day-to-day struggle facing many families, writes the Guardian. One possible conclusion that suggests is that about one third of Britons live below the poverty line or quite close to it. Does that sound like a solid conclusion to you? In fact, it could well be true. Clearly, however, there is no supporting evidence for it since the excerpt above didn't give any information about the poverty line in Britain or other important details on which to base such a conclusion.
This is a continuation of Triangles and Coordinate Plane Part I. In this part, let's see some basics with problems at the end.
Area of a triangle:
• Given three points (Ax, Ay); (Bx, By); (Cx, Cy), the area of the triangle can be found using the formula:
Area should always be positive. If we get a negative answer, we can just take the value and ignore the sign.
Introduction to Co-ordinate plane:
As discussed earlier, the topic of triangles is one of the most important on the GMAT. Questions about triangles on coordinate planes are typical of how they test students' ability by combining difficult topics. Cracking questions on triangles is tough in itself, but combining them with coordinate plane makes it even tougher to get the answer. Before directly exploring these, we should learn some fundamentals.
