Congruency
This diagram consists of two pairs of congruent shapes; two triangles in the middle of the page and two irregular shapes at the bottom of the page. A locator dot and title are shown. These must always be at the top left of the page when the image is the right way up. The top two are congruent - the one on the right is in a mirrored position. The diagram shows how their congruency is proved. The bottom two are also congruent - the one on the right is in a rotated position. When shapes are congruent they are the same size and shape but can be rotated and/or mirrored.

Rotation
This diagram shows three triangles; the original triangle and its rotation in two different directions to two new positions. A locator dot and title are shown. These must always be at the top left of the page when the image is the right way up. There is a graph with all four quadrants showing, and the x and y axes ranging from -3 to 3. The x and the y axes intersect at the origin marked by an X. Axes values are positive to the right and to the top of the diagram. Axes values are negative to the left and to the bottom of the diagram. Not all axis division marks are labelled. Some of the braille uses maths code notation. When an object is rotated it stays the same shape but its position and orientation change. The original triangle is in the top left quadrant. The triangle rotated 90? clockwise is to the right. The triangle rotated 180? anticlockwise is shown in the bottom right quadrant. Their path of movement is indicated by curved heavy dashed arc lines. Note the 90? arc in the top right quadrant is broken in the tactile version of the graph to allow a braille label to be clearly read.

Translation
This diagram shows three triangles; the original triangle and its translation in two different ways to two new positions. A locator dot and title are shown. These must always be at the top left of the page when the image is the right way up. There is a graph with all four quadrants showing, and the x and y axes ranging from -3 to 3. The x and the y axes intersect at the origin marked by an O. Axes values are positive to the right and to the top of the diagram. Axes values are negative to the left and to the bottom of the diagram. Not all axis division marks are labelled. Some of the braille uses maths code notation. When a shape is translated, it stays the same shape and orientation; only its position changes. The original triangle is in the top left quadrant. There is a translation to the right of a value of 4, and then a translation down of a value of 1. There is also a second translation, right to a value of 4, and then down to a value of 4. The movement of the first triangle is indicated by a heavy dashed line.

Enlargement
This diagram shows two triangles; the original triangle and its enlargement into a new position. A locator dot and title are shown. These must always be at the top left of the page when the image is the right way up. There is a graph with the x-axis ranging from 0 to 5 at the bottom of the page. The y-axis ranging from 0 to 6 is to the left. Every other axis division mark is labelled. Some of the braille uses maths code notation. The original triangle is in the centre of the diagram. The enlarged triangle is towards the bottom right. The heavy dotted lines indicate the tracking of the enlargement. A1B1 = 2 x AB therefore the scale factor is 2.

Hurricane areas of the world (UEB uncontracted)
by RnibThis is a multi-page image of Hurricane areas of the world, set on two pages. There are locator dots shown, which will be at the top left of each page when the images are the right way up. Key to hurricane areas of the world: This page shows the key to the diagram of hurricane areas of the world. On the left hand side of the page is a list of abbreviations for the continents of the world, listed in alphabetical order. In the middle of the page, running from top to bottom, is a line dividing the two parts of the key from each other. On the right hand side of the page are examples of the symbols, lines and textures (colours) used on the diagram. They are displayed in a column in alphabetical order with descriptive labels to the right. Hurricane areas of the world: This page shows a map of the world bounded by a dashed line image border. The land is shown by the textured areas of the map. On the left of the page are, North and South America, in the centre Europe, and on the right Asia and Australia. The heavy dashed line of the Equator runs horizontally across the middle of the page. The hurricanes and their directions are shown on the map as lines with arrowheads, which curve clockwise when up the page from the Equator and anti-clockwise when down the page. There are three of them just above the line of the Equator on the left of the page. On the right of the page, there are six above the Equator and six below.

On the left of the page is a vertical scale marked in degrees Centigrade starting from zero at the bottom. It is marked at every five degrees and labelled at every ten degrees. Running right across the page are fine horizontal grid lines. The thick dashed line representing the temperature can be found at the bottom left of the page sloping up and down to right. Across the bottom of the page are twelve labelled vertical bars showing the rainfall for each month of the year, starting with January on the left. To allow sufficient space, the braille labels are uncapitalised. At the far right of the page is a vertical scale of precipitation in millimetres, starting with zero at the bottom. This is marked every 25 mm and labelled every 50 mm.

Development of a tropical storm - cross section (UEB Contracted)
This page shows a tropical storm in cross section (cut through vertically and seen from the side). There is a locator dot shown, which will be at the top left of the page when the image is the right way up. The diagram has a dashed line image border. In the middle of the page there are arrows pointing down, and to either side of these the cross section through the clouds can be found. Going across the bottom of the page is a textured area representing the sea. The straight arrows in the middle of the page represent the flow of air down into the clear 'eye' of the storm system. To either side are textured areas of cloud. Within these textured areas, wiggly arrows show water vapour rising through the cloud from the sea. Rain is shown falling from the cloud to the sea at the bottom of the page. Three horizontal arrows, pointing right, can be found on the left of the page just above the sea. Three similar arrows, pointing left, can be found just above the sea on the right of the page. These all show airflow into the storm system.

It has a dashed line image border and a north arrow. The map is in the middle of the page and extends to the top and bottom of the page. Mainland Great Britain is to the right and separated from Ireland by the Irish Sea. The north arrow is in the top right corner of the page and is framed by an image border. Great Britain and Ireland July temperatures: This is a map of Great Britain and Ireland with a dashed line image border and a north arrow. Great Britain and Ireland are in the centre of the page extending to the top and bottom. Ireland is on the left and Britain on the right separated by the Irish Sea. There are six heavy dashed lines representing isotherms (lines of equal temperature) shown on the map. Most of these run from east to west, although two of the lines form closed loops; these are indicated by labels on the right. In the top right corner is a north arrow enclosed by a dashed line image border.
