Visit http://www.3minutemaths.co.uk/gcse-practice-papers/ Grade A*, A and B for GCSE practice questions. This video is all about enlargement by a negative scale factor and forms part of the playlist 'enlargement by negative scale factors.' The question is based on a series of GCSE enlargement by negative scale factor questions that can be downloaded here: This particular question asks for triangle A to be enlarges by a scale factor of -1.5 through 0 (the centre of origin). In this case I've used 'lines of enlargement' to draw the new shape accurately.

And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.
