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.

Who can put things right? Our super heroine, Scale Ella, uses the power of scale factor to foil the villain.
Scale Ella addresses number and operations standards and the process standard, as established by the National Council of Teachers of Mathematics (NCTM). It guides students in:
Using factors, multiples, prime factorization, and relatively prime numbers to solve problems.
Developing, analyzing, and explaining methods for solving problems involving proportions, such as scaling and finding equivalent ratios.

Grade 7th on Khan Academy: 7th grade takes much of what you learned in 6th grade to an entirely new level. In particular, you'll now learn to do everything with negative numbers (we're talking everything--adding, subtracting, multiplying, dividing, fractions, decimals... everything!). You'll also take your algebraic skills to new heights by tackling two-step equations. 7th grade is also when you start thinking about probability (which is super important for realizing that casinos and lotteries are really just ways of taking money away from people who don't know probability) and dig deeper into the world of data and statistics. Onward! (Content was selected for this grade level based on a typical curriculum in the United States.)
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
