Scroll down the page for more examples and solutions using If the center of dilation isthe origin and the scale factor is 2, graph the dilated image J'K'L'M'. GCSE Maths revision Exam paper practice & help. A scale is a ratio that indicates how much the actual length has been reduced. The result is as follows. The original shape is known as an object. It is commonly denoted as O. Reflection, rotation and enlargement from GCSE mathematics, foundation level. Rotation, and Enlargement. Calculate the scale factor. Enlargement Enlargement Three lessons on enlargement: The first is an introduction to enlargement where there is not a centre of enlargement. You can make a map by reducing the actual length of the land by the same percentage. (higher). The triangle PQR shown on the grid is the pre-image. If the center of dilation is. There are also negative scale factors in the higher GCSE only. GET SERVICE INSTANTLY. To calculate the scale factor we need to divide an enlarged length by the corresponding original length. In elementary school, students learn about enlargement and reduction. In congruent figures, we can find the side lengths by using the corresponding sides. Use tab to navigate through the menu items. On the other hand, when a figure is made smaller, it is a reduction. Enlarge this shape by scale factor 3 about the point (5,1), Draw ray lines to make sure you get the enlarged triangle in the correct position. When you make a figure larger, it is an enlargement. Thus, we see that 2 km is the answer. Calculate the scale factor. 3. The centre of enlargement. Extend the ray lines. Examples: The third lesson looks at enlarging shapes from a centre of enlargement by fractional and negative scale factors. Use the ray lines to help you enlarge the shape. the origin and the scale factor is 3, graph the dilated image A'B'C'. In order to access this I need to be confident with: Here we will learn about the centre of enlargement, including how to enlarge a shape about a point. It is used often as the centre of enlargement. The scale factor, a. Includes reasoning and applied questions. Here triangle ABC has been enlarged by scale factor 2 about a centre of enlargement point O. 3. An example on how to enlarge a shape by a positive and negative Choose a point to start with. If you are asked to give a single transformation make sure it is a single transformation, not 2 or more. Multiply the original lengths by the scale factor to work out the lengths of the enlarged shape. Please read our, Example 1: use a scale factor to enlarge a shape, Example 3: with a centre of enlargement on a grid, Example 4: with a centre of enlargement on a coordinate grid, Example 6: negative scale factor (HIGHER), Enlarge a shape by a scale factor on a grid, Use a centre of enlargement to enlarge a shape on a grid, Use a centre of enlargement to enlarge a shape with a fractional scale factor, Use a centre of enlargement to enlarge a shape with a negative scale factor (higher). The point O is the origin. Triangle A has been enlarged by scale factor -3 about the point O. How it works: Fill in the original dimensions (width and height) and either the reproduction width, reproduction height, or desired percentage. (a) Enlarge triangle T by scale factor 3, centre the origin. Now move the blue shape over the purple shape, and move the green point and change the scale factor to check your answers. Moveable centre of enlargement. The scale factor is 2 , so each of the sides of the enlarged triangle should be double the sides of the original triangle. The increase in size from one shape. if the side length is doubled, the corresponding side is doubled. Then, lets change the unit from cm to km. Choose a point to start with. The scale factor is \frac{1}{2} so the triangle gets smaller. As you can see, the lengths of all the sides are doubled.

Thats why we use a scale to show the world in a much smaller size. Draw ray lines going through point B and point C.Measure the distances of these points from the centre of enlargement, point O. Each line in the image is parallel to the corresponding line in the object. Scale \ factor = \frac{enlarged \ length}{ original \ length}=\frac{2}{1}=2. Sometimes we make a shape bigger or smaller. How it works: Fill in the original DPI and the reduction or enlargement percentage and click Calculate to receive the new, modified DPI. What is the transformation? Enlarge the shaded shape with scale factor -1 about the point. \text{scale factor } = \frac{enlarged \ length}{ original \ length}=\frac{6}{2}=3. Measure this new distance from point O and put a mark for the new point. How to translate a shape given the translation vector? If an enlargement has a scale factor of 2, each side of the image is 2 times larger than the sides of the object.
