Enlargement negative scale factor

B1 for enlargement B1 for scale factor -1 B1 for (0, 1) (NB: a combination of transformations gets B0).Secondly, enlargements may involve the use of negative scale factors.

Key Stage 4 Mathematics - At Key Stage 4 we continue to develop students Mathematical skills.For example, if the length of a shape is 2x the length of the original shape, it has an enlarged scale factor of 2.And if the scale factor is less than negative 1, meaning a large negative number, this is an enlargement. 00:07:16 Comparing these two, the difference between the negative scale factor and positive scale factor just makes a difference in which direction the ray of the dilation is going.In order to enlarge a shape with a negative scale factor: a) First make sure that you have marked on the centre of enlargement onto your coordinate grid. b) Next count the distance from the centre of enlargement to one of the corners of your shape.

A dilation is an enlargement if and only if the scale factor is greater than 1 or less than -1.

Scale Factor 2 If the scale factor is between 0 and 1, the image is a reduction (a shrink).Have several groups share their observations with the class. (Students should note that each leaf of the fern is a dilation. The.With a negative scale factor the number part of it tells us if the shape is to be made bigger or smaller, while the negative sign tells us that the image and object are on opposite sides of the centre of enlargement.


When the dilation is an enlargement, the scale factor is greater than 1.We already know how to draw an enlargement with a positive whole number scale factor.A scale factor which to creates an image larger than the original is called an enlargement.

It is a gold mine that is a must for any students preparing for any mathematics qualifications.

Students follow the Edexcel Maths syllabus and have the opportunity of sitting either the Higher or Foundation papers at the end of Year 11.Because absolute values are always positive, the absolute value of this scale factor is positive 2, causing our image to be twice as large as the pre-image.

If the scale factor, k, is greater than 1, the image is an enlargement (a stretch).

Students learn how to perform and describe enlargements on a grid using a centre and scale factor.What this means is that if you have a scale factor of 3, or sometimes written as 1:3, the image is three times bigger proportionally to the pre-image.

Scale Factor of Enlargement = Length of either side of the image Length of the correspondingside of the object In case of positive or negative scale factor of the enlargement, arrangement is as under: Scale factor K Arrangement Size of Image Direction of the Image 0 < K < 1 Centre Image Object diminished Erect K > 1 Centre Object Image Enlarged Erect -1 < K < 0 Image Centre Object diminished...Grade 1 Grade 2 Grade 3 Grade 4 Grade 5 Grade 6 Grade 7 Grade 8 Grade 9 2015 GCSE Syllabus Worksheets Clicking on something like this will take you to the Grade 4 clip numbers and titles.A scale factor which creates an image smaller than the original is called a reduction.In this case, negative scale factors can be given, in which case the new distance is measured in the opposite direction from the centre of enlargement.

Further information on the contents of the packs or to preview the cards on the website This pack contains over 120 revision cards.Enlargement is when a shape is larger by a corresponding length to the original shape by a specific scale factor.So, if the scale factor is three, then the dimensions of the new shape will be three times larger than that of the original.

An enlargement is a transformation that produces an image that is the same shape as the original, but is a different size.
