GRAPHING ENLARGEMENTS When a dilation in the coordinate plane has the origin as the center of dilation, we can find points on the dilated image by multiplying the x and y coordinates of the original figure by the scale factor. (c) Reflect shape A in the line x = 3 and label it shape D. Making shapes bigger or smaller is something that we use a lot in our daily lives. Find the centre of enlargement. Also, if one side is $\displaystyle\frac{1}{3}$ times in length, all sides will be $\displaystyle\frac{1}{3}$ times in length. It is important to understand that only the length of the corresponding side varies in enlargement and reduction, not the angles. the origin and the scale factor is 2, graph the dilated image J'K'L'M'. The size of the figure depends on how many times the length of the sides is increased. The lengths in triangle A'B'C' are three times as long as. For example, if the scale factor is 'k', the algebraic representation of the dilation is (x, y) (kx, ky) reduction is the opposite of enlargement. Use the pen tool to draw the following enlargements of the purple shape : scale factor 2 about the purple point On the grid, draw an enlargement of the rectangle with scale factor 3.

The lengths of the sides of the new shape are double the lengths of the sides of the original shape. Enlarge the shaded shape with scale factor -2 about the point. Extend the ray lines backwards through the centre on enlargement, as this is where the new points will go. Point A is a good place to start as it is straight up from the centre of enlargement, point O. Multiply the distance by the scale factor 3. Measure the distance from point O to point A. Since the scale factor is 3, the rule to get, the coordinates of the vertices of the image is, The rectangle JKLM shown on the grid is the pre-image. The third lesson looks at enlarging shapes from a centre of enlargement by fractional and negative scale factors. You may also be asked to find the scale factor of enlargement. So to make it an actual length, we should multiply it by 20000. Enlarge the triangle ABC by scale factor 2 about the point O. How it works: Fill in the original DPI and the reduction or enlargement percentage and click Calculate to receive the new, modified DPI. Find out more about our GCSE maths revision programme.

(b) Triangle PQR is enlarged by scale factor -3 with centre of enlargement C(4,5). An enlargement makes a shape larger or smaller. How to translate a shape given the translation vector? Use the ray lines to help you enlarge the shape. Example: Properties of Enlargement. Draw ray lines from the centre of enlargement through the vertices of the original shape. Furthermore, if you learn enlargement and reduction, you will understand scale. 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. The original shape is known as an object. Rotate ABC about (0,-1) by 90 clockwise. Therefore, the length of $b$ is 4 cm. Then, lets change the unit from cm to km. This video shows how to transform a shape using a given translation vector. The Length of the Corresponding Side Varies. You can also add, subtraction, multiply, and divide and complete any arithmetic you need. They can overlap. If the center of dilation is. Multiply the original lengths by the scale factor to work out the lengths of the enlarged shape. As you can see, the lengths of all the sides are doubled. Therefore, there are corresponding sides in enlargement and reduction. Label the image C. Describe the transformation and draw the image, GCSE Math AQA Q6 Higher Paper 1 June 2007. So, lets understand that the length of the corresponding sides changes. I only wish the other vendors we work with were as thoughtful and conscientious as y'all. not change in any other way. Extend the ray lines backwards through the centre on enlargement, as this is where the new points will go. For this example the scale factor of enlargement is 2. Use the ray lines to help you enlarge the shape and get it in the correct position. Draw ray lines through the pairs of points. in exactly the same way. If we use the heights of the rectangles: 3. The ratio of the lengths of the corresponding sides is the same in enlargement and reduction. All rights reserved.Third Space Learning is the trading name of Virtual Class Ltd. When you make a figure larger, it is an enlargement. When an object is enlarged the object and the image are similar shapes. Related Pages 4. An enlargement resizes a shape.

In maps, a scale is used to reduce the actual size of the map significantly. The scale factor, a. Enlarge this shape by scale factor 2 about the point O. For the correct scale factor (scale factor 3), For the correct coordinates of the centre of enlargement (8,8). Calculate the scale factor. Use the pen tool to draw the following enlargements of the purple shape: Since the scale factor is negative 1 we mark the point A measuring backwards along the ray line from point O. The angles in the two shapes are the same and the triangles are similar triangles. Find a pair of corresponding vertices and draw a ray line going through the points. So lets try to understand the relationship between enlargement and reduction and the concept of scale. Therefore, 200000 cm is 2000 m. Also, 1 km is 1000 m. Therefore, 2000 m is 2 km.

There are also enlargement worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if youre still stuck. For example, a scale factor of 1 2 will also enlarge a shape on the other side of the center of enlargement and turned upside down. In enlargement and reduction, the shapes must be the same. Also, the ratios of the corresponding sides are the same; if you look at A and B, you can see that doubling the side of A makes the side of B. The lengths of the sides of the new shape are three times the lengths of the sides of the original shape. The centre of enlargement is point P. Choose a point to start with. Each line in the image is parallel to the corresponding line in the object. An enlargement is a type of transformation .
